A bit more info on how you play; you like soloing? I'll get back to that.
I have the Roadster head so I'll throw in my 2 cents. First, the Roadster combo is a H-E-A-V-Y amp. Check the specs. The Head is reasonably heavy on it's own at around 22kg. A 2x12 Cab is around 27.5kg and 'reasonably' compact. So maybe consider the benefits of a separate head/cab for weight reasons. Best to save your back if you're moving and lifting amps around.
Wattage: Roadster is 100W.... also has 50W setting. If it's what you need, then great.
Sounds: Great sound and tone but needs work and understanding how to dial it in. Best advice I've read on this site: close your eyes and dial it in.... seems to be the 'norm' for Mesa amps. If you look at the dials and dial it in as say, a Marshall, you'll probably be disappointed. The tone controls B,M,T are 'interactive' with each other and moving one affects the other. Increasing gain and volume also affects the tone.
With these amps, low volume can sound fizzy/buzzy and may annoy you trying to dial this out. High volume makes recto amps sing, so if you're after low volume and expect 'something great' best to consider other options such as the mini-Rec or mini-Mark. Software emulations sound great at any volume because they have to.... you're not expected to crank volume on your headset damaging your ears so they have to sound good at most volume levels. Real amps vs emulations can be (and are) very different beasts. ANother thing is emulations don't really have that fizziness and buzziness.... they are always emulated to sound 'the best' as per a real amp sounding it's 'best'.... so consider that, too.
I'll get back to my first statement: I've always said recto amps are great rhythm machines.... they really pump and sound huge. For soloing, I find they lack fluidity and sustain... don't expect 'Santana-violin-type' lead sounds. The amp can sound and play a bit 'stiff'. For example, hammer-ons / pull-offs / legato playing could be a bit troublesome; the notes can sound 'staccato-ish', so to speak, because the amps is dynamic and very unforgiving. The amp needs help in this department and a good overdrive pedal can help here. Many use TS-type pedals to tighten up the tone and depending how it's set can compress the signal a little bit for 'lead' sounds. I use a combination of pedals, sometimes cascading one into another. One pedal is to push the amp so it still sounds 'natural' but makes it a bit easier to play and the other I kick in for lead playing so I don't feel like I'm fighting the amp. I find a very small amount of compression helps, too, just to even out the dynamics a bit when having the gain low. All my gear is controlled by midi-foot contoller and midi-patchbay. It's just easier foe me but a simple setup is possible, too.
Just another bit of info that can maybe help: an EQ in front and in the loop can do wonders if you're having trouble with the tone. Both EQ's do different things; the front end EQ can be shaped to push certain frequencies to drive earlier (or drive more) for example. One in the loop can be used to control the overall tone or act as a volume boost or cut.
Now, the bands you've listed aren't 'recto' playing bands (in my head I *think* Alex of Rush used one at one stage but I could be wrong). Marshall is pretty much the norm here so *don't* expect to get a recto to sound like a Marshall. You can 'kind-of' get there but you'll never get there. I've got close with pedals, experimenting using the Clean-Pushed channel on the Rectoverb amp I had; I can get close on the Roadster for sure but I haven't tried yet. Most likely the Ch1 or 2 Tweed or Brit mode would do it, I'm sure. I've got heaps of pedals to experiment with so I'm definitely not short of anything. Unfortunately I can't tell you what pedal or combination of pedals gets very close for an ACDC type sound, for example.
If at all possible and make a serious attempt because it's money your spending, test drive a real amp rather than listen to software based simulations, they are very different and each have their use and purposes.
You've also stated that it'll be a 'bedroom' amp...... TBH, a Roadster isn't a bedroom amp. It's a great amp for sure and commands it's own space and volume, as most powerful amps do. The cool factor is there, no doubt, but the cool factor can quickly become a disappointment, too.
Consider the above points and anything else others write. Don't just buy the amp because it's a Mesa and it's the coolest amp in the street. Buy an amp that will do what you want it to do. Emotional versus practical are very different things and they don't often meet.
Anyway, hope you get more responses and advice.
