I should probably post this as a rave/rant, but the Infinity Beta 20s have been in low/nonexistent supply, and are no longer the "super deal" that everyone on AVS and Audioholics say. a 5.0 Beta 20 setup is no longer attainable at $50 / speaker.
I bought a single Beta 20 when there were still some left for $60 shipped, but shortly afterwards, the Harman outlet stopped stocking them. Once in a while they'll pop up, but they'll go for about $85-$90 shipped. Check ebay right now, there's barely anything.
The next lowest price would be Tigerdirect/Systemax/Circuit City, at $129 a pair, which is a great deal until you see that shipping is $77 (at least to California).
At a price higher than $70 shipped each, I'd rather spend my money on other speakers (I tried selling the single I have but haven't had any takers). Just seeing if there's anyone around that wanted to offshore/upgrade.
