When I was doing wha you're about to do, I joined the DIY Loudspeakers list. They get discounts from several suppliers, including Madisound and Avatar. You also get buried in email, but you can unsubscribe after getting the info you need. I'm happy with my Avatars--forget the model name. But you'll have lots of choices and lots of "experts" to advise you, some of whom are doubtless really experts. I can't tell you where on the Web to find the list, but get back to me if a search doesn't turn it up. (Audiogon allows that, doesn't it? I've never tried.)
