This is a somewhat unorthodox answer, but for truly cost effective and reliable FXO functionality, you cannot beat (used/unlocked) Linksys RTP300. It has a 4 port switch built in which may or may not be usefull. But for 2 FXO ports you can't beat it for around $10-$12 on EBAY (or new around $50 - $75). I have used these for home adapters for my house and several others for years. They are quite reliable. They support NATing just fine. Just something to consider.
