Go with a tube amp. The "maintenence" issue is way overstated. You don't have to change your tubes every year by any means... especially if you're mostly playing at home. Your tubes will work fine for years... If using new production tubes, I'll usually change the power tubes once every 2 years, and I play out (gig) actually about 3-5 times a week. If using NOS (new old stock) or used American made or British made tubes, I NEVER change the tubes unless I can detect a drop in performance. These old tubes last a long time, sound better, and pay for themselves shortly. Preamp tubes should never be replaced unless they are malfunctioning; there is simply no reason to.
Tube amps are not substantially more fragile than solid state. Actually I find them to be more durable (especially vintage types) as they are typically simpler in design and constructed more with the professional in mind. A vintage Fender amp, for instance, is like a chevy... if it breaks down nearly anyone can pop the hood and figure out what's wrong with relative ease. When a tube amp does go down, it's 95% of the time a matter of a bad tube... swapping is easy. With quality tubes this rarely happens, especially if you're not taking the amp around all the time. All my Fender amps (except for the pro jr.) are from the 60s and have been virtually maintenence free since I got them. AND they have all been gigged regularly! A solid state amp, on the other hand, if it goes down... it usually goes WAY down... often to the point where there's no point in the cost of fixing it.
I would look into vintage Ampeg amps if I were you. They're typically still available cheaply, and the 7591 tubes that they use are now being made again by JJ/Tesla, so tube compatibility is no longer a problem. You might think of getting one before the price goes up, as the 7591 issue has been until now the main thing keeping the cost down. You could get an old Jet J-12R for very reasonable $$$ and (while no distortion circuit if you need that) it sounds great... offers a great distortion tone if you turn it up. I like to use an old tube amp and drive the front end with a ZVEX Super Hard-On or other boost pedal as my "distortion channel." Works well!
Try out the Deville, try a pro jr., and keep your eye out for any vintage tube amp that's reasonably priced and give it a try! Only you can know what you need.
The only reason I asked about style was for the purpose of "do you need mondo crunch gain" which it sounds like you do not. Good luck.
Go with a tube amp. A pair of JJ/Tesla EL-84s (as in a pro jr.) every two years will cost you maybe $15.95 at Tube Depot, maybe less elsewhere. Worth it!
