ok im getting more informed about home theater everyday but im still sort of new. im a college student who wants to make my own stereo. i realize that i can get better sound out of component pieces than if i buy a big boombox. my budget is limited to a couple hundred bucks $500 at the absolute max. i know most of you reading this are thinking what the heck can he get thats halfway decent for $500. im totally fine with used. what im looking for is a receiver or a pre-amp either one (i don't listen to much radio though). and a decent set of bookshelfs preferably but i guess floor standing would work too. i have a music source, either my ipod or my laptop. so i don't need a cd player or anything. can anyone point me to a good used stereo website or maybe somebody has something lying around the house that you would be willing to let go of for a price.
