You might pay more, but you're getting something for it, the ability to audition, and to have local support. That is a good thing to have, especially for receivers and projectors, which tend to be some more of the pricier tidbits in one's media room/theater.
That being said, I bought my Marantz 8001, site-unseen from acc4less. I took a shortcut, and I lucked out. I love the Marantz, but I sure wouldn't mind a 3808
