+1 to ebay picked up a toomey w/ flange in nice shape for $99 shipped.
I also saw a power pros w/ flange and silencer nice shape as well for $133 plus shipping.
I took my dg pipe and flange, which was in good shape but showing its age, wire brushed it and wiped it down with 30 weight and a clean rag asked $100 and it sold in 20 minutes.
Given I waited and watched for almost 3 weeks before hitting on the B1.
