If you watch for it you'll find them. I've bought (and sold) too many good O/U's that were a good deal. Last year I found a used 12g/30" SKB with tubes on Cabelas gun library for ~$625. It has some warts but is very solid. A sale was on and there were some delays at the store so I ended up getting it for $550. Several years ago I bought a 12g/28' Citori with tubes from an older gentleman in Cleveland for about $650. They're out there but you have to beat the bushes to find them. Good luck!
