Asterisk as a "Legacy PBX"

cleveoh

I'm incorporating Asterisk into my lab as a "legacy PBX", anybody have any info as to a good cheap FSX/FXO card? I'm looking at purchasing this card Openvox A400P 1 FXS/FXO Digium Asterisk Trixbox TDM400P - eBay (item 300330381932 end time Jul-04-11 14:03:30 PDT)
