yeah... I've had pretty good luck so far with eBay.
I got a bass, tuner, keyboard, mic cords, CDRom recorder etc... everything was just as advertised and really good prices.
About the only thing I'd watch out for are ordering stuff over the border (my CDRom cost about 75% extra in taxes and duty) and ordering RAM memory. (bought it at half price & it works ok, but it's sloooow)
