I haven't tried one, but they get good reviews. Vintage meets modern - basically a synchronised trem with lock down saddles. Stewmac only sell the version with the cast block though. If you want steel, you may have to look around.
Gotoh also do a version which is a standard vintage trem in every way but for the two stud mounting. That'll be closest to the Musicman.
I've got a
Wilky VSV400P, which is very nice. Comfortable to play on.
