Ya, i just got a new U4 today.
I bought my wife a U1 28ga a year ago,
They're awesome guns for the $$$.
Lot's of people on these forums have bought Dehaan's.
The only downside (if you can really say there is a downside)
Is that you can't go into any store and look and feel one, unless you go to Dehaan's in Idaho.
They only ship them direct, you have to go to your local gun store and get a copy of their FFL license,send that to Mark Dehaan with your check for the gun, and he will ship the gun to that gun shop, the gun shop will usually charge a fee $15 to $25 for the transfer.
But you wont be disappointed when it arrives.
