I have Stoeger Condor. Picked it up at Dicks for $400 shoots great not a bad looking gun either. They make it with both 12 and 20 guage barrels for $550. I have only put about 2500 rounds through it. Never had a problem with.
+1 on the Stoeger mine is close to 3k rounds and looks and shoots and locks up like new. I also have one of the first run Mossberg silver reserves in 12ga o/u its close to 10k rounds now and has never missed a lick either.
