I hope to see more replies because I was in your situation some years ago.
I'm far from an expert, but in my experience, at _that_ price range you
don't have a lot of products to choose from, the Cisco SPA3102 is
similar to what you are describing (Plus it's also a PSTN GW). Of this
kind, I used GXW-4004 and Linksys PAP2, SPA3000 (the Cisco 3102
predecesor), also some larger AddPac ATAs (www.addpac.com) with
excellent results, all of them have their pros and cons. The Digium
TDM410 cards and they have a very good price/quality relation, plus they
are intended for asterisk, plus you are supporting asterisk development.
