I use the Metz MZ-54 and sync cable- works well, though the cables seem rather expensive for things that are really un-reliable. I usually use the flash on the grip socket, but truthfully, it can go on the top as well, and just as easily. I rarely dig out the finders for the various lenses- there's just too much to track with that camera.
Sad to hear about the theft. Of all my cameras, it's the only set that haven't suffered from my GAS. I've all the lenses except the ones I don't care for (the 100 f/3.5 and 90mm) and lots of backs, finders, accessories, &c. It's worth coveting. 🙂
