Hey all, I'm interested in buying one of this line 6 wireless systems but I just have a couple of question, Is there really a big advantage between the g50 and g30? I know the g50 has a longer range, and it has metal casing, other than that, does the plastic battery door from the g30 really cheap? Has anybody broken their battery door or transmitter? Is the connection (4 pins inside) of the g50 transmitter can break easy? And one last thing, is there a way to measure the battery life of the g30?Thanks in advance.
