Petrela, I agree, provided you avoid SS unless you can replace the electrolytic caps yourself, and make sure they are available. Old "tube" equipment might be the best buy, but when you take into consideration high priced repair, that might not be a good idea either.
I recently bought an amp for the bedroom from "Parts Express", and was quite pleasantly surprised. For the main listening room I have PrimaLuna mono blocks, and I love them. People on a budget are between a rock and a hard spot when it comes to the "high end".
Those prices are the result of this hobby being invaded by too many people who know why they don't show prices anymore on a lot of gear; "If you have to ask, you can not afford it".
