I have a 1222FX-Pro I use at church. The quality seems excellent. The FX section is very adequate. Although I don't have need for many effects, I do use the Ambience program with no problems. The congregation has given me many positive comments regarding the choir sound since we've gotten our new equipment. This is one of the reasons I wanted experienced feedback on the Alesis. I have heard there are some quality issues also, but IMHO there is nothing better than hearing from an actual user or seller.
