I would advise you to get a Mark III Simul-class, EQ, and Reverb. Opt for the EVM if you get a combo. If you get a combo, track down a 112 EVM Theile cab. The Theile is a MUST for a combo. If you get a head version, then a 212 Half-back cab is perfect if you don't want to lug a 412. Look for one with a C90/EVM combination.
I have a 200-watt Coliseum Mark III half-stack--I've used it in plenty of smaller clubs. It's very controllable. I use a compressor with this amp to tame the dynamics. Yes, it will get very loud; but this amp has explosive dynamics, and a compressor gives it more of a small amp feel.
I honestly don't think the full power setting of a Simul-class amp will be too much for you. Unlike some amps, these amps have a smooth pot taper at lower settings, so low volumes can be easily controlled.
A fully equipped Simul-class Mark III will always have the best resale compared to the 60- or 100-watt versions.
As to stripes, each version has its fans--I've never gotten a definitive answer to there being a "best" version; but I like my combo a lot.
If you want more control over the power amp levels, then by all means consider a Mark IV. With the Simul-Class/Class A, Full/Tweed, Pentode/Triode options you have a lot more range than on a Mark III. The learning curve is steeper, but if you are patient--it can be a very rewarding amp.
Good luck in your quest.
