But its a good amp I was thinking about getting one for a while but eventually settled on a Deville.
and tube amps are really nothing to fuss over. If something goes wrong, generally it will be easier, and cheaper to fix than if you were using a solid state amp. The only real downside to using tube amps is that you need to replace the tubes after regular use but unless you constantly push them to their absolute limits then you shouldn't need to do this frequently. They also do tend to be heavier but there are ways around that.
Also, just curious but why do you need a guitar with a floyd rose? IMO they are only really useful for metal and if that is what you want to play then you shouldn't be getting a twin reverb since you could get something much more specialized for a similar price. Don't get me wrong, floyd rose's are great but they are meant for really heavy use and you have to pay for that sort of functionality with usability in other aspects.
The Twin Reverb is an awesome amp. Did you eventually get one? Honestly, I'd check craigslist for a used one and save yourself a bundle.
Tube amps can be awesome (the one you chose definitely is) but I'm also curious about what you're playing -- superunknown above asked the right questions.
If you're wanting a shredder for a guitar, I wouldn't think a Twin Reverb would be on your list of amp choices. But to answer your question, if I were getting another guitar with a Floyd, I wouldn't go cheap. I have yet to play one that was durable unless it was an original USA-made version. That said, I haven't played every model. But those that I have played have worn and become sloppy very quickly.
YMMV, but I thought I'd throw that out there -- get the top-of-the-line Floyd or wait...
