I can't spend more than, maybe 0. For my price range, would new or vintage speakers be a better choice? Why? I found some polk's at future shop that I like, but can't really compare them to vintage very well, and I'm not sure what the difference is.

Ya, I'm not gonna hold my breath for a pair of 70's pioneer speakers in working condition to turn up at a yard sale in the next two weeks, and getting them off ebay would cost a fortune in shipping.
