The G50 has more channels - 12, instead of the 6 for the G30.
Also, the G50's transmitter is made of metal, while for the G30 it's plastic. They use a different connector too for the short cable to the bass, don't know what difference that would make though.
I'm a G50 user - and I think it's the best bit of kit I've ever bought. Bonus is it happily takes a Boss-type power supply so it's ideal for my pedal board.
Edit: the G90 has a much bigger receiver - could be for rackmount, but I'm not sure.

Yep, the G90 is a rackmount reciever. I'm going for the G50 myself (When i can afford it) and it's going to get stuck on my pedalboard (When i can afford that too) so i want the metal casing over the plastic of the G30. Hopefully wont be too long till i can, always scouting around for a used one on here too.
