Heh, I've found more shortswords than any other weapon type, to be honest. A lot of good ones, though, you'll need to dig in max-spawn dungeons to find.
As for sneak items in general, it's pretty much been a bumpy ride for today's rogue. Yesterday's rogue had access to sneak-gear that today's rogue can't get unless they get lucky enough to be handed down stuff from yesterday's, or if a DM gives them a quest to obtain such.
