I've also considered one of the CG guns. I've looked at them every opportunity I've had to pick one up. I haven't found any reason to believe they aren't built very well for the money. I haven't seen the guts of one, but all the visible outsides are very well done.

The 2 bbl 20/28g has appealed to me, and now they're doing a 3bbl set 20/28/.410 in 28" tubes that looks like a nice setup to me.
