60W is fine as long as the price is right. They're brighter sounding that simul-class amps (I actually prefer the 100W to simul and usually have my 100W switched down to 60W as it's already loud enough and get slightly more plate voltage that way) but I would be more concerned about lack of EQ as the circuit definitely adds a more defined sound than having an EQ pedal in the loop.
I'd also recommend a black or purple stripe and get it modded than a red or later due to a later circuit board revision (not all stripes are the same!). Depends what kind of sound you're after?
I generally go on a basis of starting with the max I would pay for a fully loaded simulclass (DRG) then reduce the price based on which features it doesn't have with graphic EQ being the most important in my opinion (reverb not so much as). So price wise it'd be:
DRG (Simul-class, Reverb, Graphic)
HRG (Hundred watt, Reverb, Graphic)
SRG (Sixty watt, Reverb, Graphic)
DG (etc.)
HG
SG
DR
HR
SR
D
H
S
So I'm guessing this is a 60W with no graphic or reverb (S)? If so unless the price is an absolute steal (I'd also be cautious as to why it's priced so low) I'd look for one with at least a Graphic EQ in my opinion and go for an earlier Black or Purple if possible and get it modded.
