Moach,
There aren't many around, unfortuntely. The recent FFX DC-10 doesn't have one, nor do the Project Opensky or MelJet models.
There are a couple for FS2002 though:
Airbus A300 (Project Airbus) has a reasonable VC, and there's an A319 out there by FFG, but the VC is very basic - no cockpit details, just grey shapes.
There's also Nick Pike's C4-SST fictional supersonic transport (available at here SimV) which has a very good VC, and is fun to fly.
Otherwise, unfortunately, you're pretty much stuck with the default models for a good VC. Adding some better flight dynamics and a repaint might make the default models more acceptable, though. I think that adding VCs (which has to be done at the model stage) is pretty tricky.
