Yup. As reluctant as I am to classify myself as a "business" selling or buying here, A'gon stands alone as the site best suited toward doing so. US Audiomart is fair at best, and although a lot of the equipment advertised here appears there as well, it is far simpler to communicate with people here. What I do like about that site is the ability to sort searches by state, something which A'gon should implement toot-suite. [sp?] ( A while back you COULD search within a geographical define by typing in a zip code, but that disappeared with nary a word to the unwise. )
By the way, have you purchased any amplification yet?
