There aren't any bad 28 gauge guns, including Parker Repros. Somebody is out there with a Parker Repro with a Miller (Howard & Delbert) Single Trigger and a true oil finish.
It is about as nice a P.R. as you'll find anywhere. It took two years to get it to where it was an incredible gun but it is now. It will never misfire...ever. After all I went through to get it there, it took all the fun out of owning it and was moved to pay to for an ICD. I've never looked back.
I have two Ithaca Classic Doubles in 28ga and have are my primary grouse/woodcock guns. I bought an RBL-28 as a rainy day/backup gun but, you know, they are pretty nice guns and well worth the money in spite of some comments made here. At 5lbs, 14oz, with 30" bbls, you wonn't kill yourself carrying it either. It's choked Skeet/IC and is grouse poison.
