Hey Mike, I deal with the same issue of being in the country... that being said, a 4hrs trip to the store helped me pick a TC50 a few years back. I am not a Mesa amp expert like some others here so keep that in mind with my comments: I never looked back.
I played around with some tubes and the most recent revelation was thanks to
@bandit2013 (12AT7 from JAN Philips). That single tube change my amp sound improve a lot. Not a necessity but something to keep in mind if you go the Triple Crown route.
I owned different amps in the past, Marshall JCM800 from the 80's (2210?), a Mesa DC10, solid state amps with tube preamps, different 412s, etc. Why I chime in is because the TC has this versatility and potential to sound both British and American but with its Mesa signature IMO. On channel 2 you'll definitely find Marshall-ish sounds... but with a boost before the amp or EQ in the FX it will totally change its color to something else. Channel 3 is a Mesa channel for sure... in CH 1 you may find Fender-ish / Vox-ish tones. Hard to describe perfectly... I regret not getting the TC100 but I am super happy with my TC50 and how it can be so versatile by itself, even more so with added pedals and one single tube swap.
And then there is a toggle switch that will tighten your sound and open the door to gain madness if that's what you look for. CH3 on tight, with the right guitar, will bring you to Punk in Drublic sounds, super close to the Recto's (I guess) they were using then.
Let us know what you settled for! All the best and remember, you can't go wrong with either a Bandlander or TC... it's a MESA!!!
Cheers,
