Where are you located?
Brian @ PFI did mine for me and I've been happy with it. He's located in the Ogden/Layton area. I'll post some pics of mine when I get home from work

Also, I think that Kushnapup would be cool, but it doesn't work well with drums (its pretty much impossible to shoulderfire the gun with a drum). Also, I've heard some complaints of mushy triggers, however no bullpup is going to compare to a nice AR-15 trigger.
