I've owned several, both SST and DT. Had a doubling problem with a 28ga SST, which was really a shame, because I liked the gun a lot. Only happened if I fired the R barrel first, at least initially. Then started doing it even if I fired the L barrel first. Sent it off to be worked on, functioned OK for a couple rounds of skeet after I got it back. Beyond that, don't know because I traded it--due to a couple other issues, not the fault of the gun but rather of poor gunsmithing by an individual who's usually pretty highly regarded here. (Those issues not trigger related.) I wouldn't hesitate to buy another one, but I'd wait for one with DT--which I like better anyway.
If you look on p.3 of the Ithaca Classic Doubles thread, you'll find someone who had what sounds like a pretty serious issue with a Repro SST.
