so where would be a good place to get some used receivers?

well i'm in the market for a new receiver and i'm just not sure how to shop for a good one. i know that output ratings, features, and connections are one thing to look for but is there anything else? also how do i tell if a receiver is good? is it just by the sound quality they put out? and can i get some suggestions on which ones to get? it doesn't really matter what brand. my budget is about $300 but i can go a litte bit over. thanks...
