Best Center Channel Speaker

Looking for a really good 2 channel speaker, have the Vandersteen VCC1 now but looking for something better, will spend 600-800 used. Any suggestions will be greatly appreciated. Rick
Aerial CC3. Provides environment control for positioning above below monitor, or on stand (prefered), and a program adjustment for midrange cut/boost that can also serve to intergrate the center with your main speakers. Ultimately though, you would want consistent or identical speakers for good HT. If your main focus is on 2 channel, the Aerial gets you more dialogue, detail, and authority than anything else I've heard, and blends well with a variety of other speakers.
Thanks to all for your responses so far. I should have mentioned that my main speakers are Vandy 2CE's. Will the Legacy Silver Screen work? Thanks again for all the help. Rick
