As to American-made tube integrateds, I think the VTL IT-85 and the Manley Stingray are great, and easily found used in your price range. As other posters have suggested, Cary and Rogue are also decent performers (in a number of models) in your price range. All of them will have a slightly different sound.
Buconero117,
I am interested in this legislation. The question is if it is mostly built in one place (like China), bought FOB for $200, is shipped to the US "mfr" who takes it out of the box, inspects it, gives it a good rubdown with a dry cloth, adds a fancy brass plate on the back, and reboxes it, and sells it to his distributor for $600, how much 'content' is US and how much is non-US? I foresee no issues whatsoever at the low end, and a lot of potential issues at the top end.
