After a week long learning process, I bit the bullet and bought the Denon E-300 receiver. It seemed like a bargain at $279. But now I need advice to complete my first home theater with the best possible sound, while trying to keep the entire package around the $500 limit. Is it possible to get a decent subwoofer, center speaker, front & rear speakers for $220? I considered the Sony SS, DV-62CLRS and Dayton Sub-1000, but they pushed me way over my desired limit. Any good alternatives? (and no, I don't live near a sony store where I could seek used speakers.) Thanks for any advice you can give.
