5 or 6 months later, I'm still really happy with my G30. I definitely need to get myself one of those levy's wireless holder jobbies though, I've taken to taping the transmitter to my strap with electricians tape at every gig. The wireless holder is £20 on Amazon at the moment.
I did find out the source of my range troubles, and that was down to me being a dipstick and having my smartphone next to the receiver, which seemed to interfere with the signal. Range is now excellent.
Being wireless is glorious, even if only for the chance to carry on playing while jogging round the pub like a muppet to puzzled looks from punters.
