It comes with composite out, which should work fine any US TV that takes that. The controller cord length does blow, but there is a connector for third party controllers. However, it's not directly compatible with US controllers, though Google informs me that some people have made mods. For issues with the console, make absolutely sure they've tested the disk drive. The original belts basically melt with age (seriously, I tried changing one once, and I had to scrape it out), so any Twin Famicom will have to have been repaired at some point to work now.
For recommendations, Ai Senshi Nicole is a great overhead action game from Konami. It plays a lot like the overhead parts of The Guardian Legend. Hudson's Binary land is the big hidden gem of the first few years of the Famicom and one of my favorite games on the console. Even if you already have cart versions, it's worth grabbing the disk versions of Metroid and Kid Icarus if you like those games at all, since they have better music and save your game rather than requiring passwords.
