These should all be in your price range. I have no interests in any of these auctions.

For the 10ga, get set of Little Skeeters. Grind one side to allow the ejector to grab the shell, then use loctite to hold them in place. Or spend a few dollars more and get chambermates.

No need to hunt in shame... unless you do this to it:
