There's a considerable difference between the E60 and G70's Internal memory size... after the ROM styles are in the E60's memory (it shares it with user data) there is not too much room left). However, it still has a card slot, and external memory functions identically to Internal, so it shouldn't really be a problem...

The E60 has exactly the same single stereo out as the E80... If this made the decision for you, if you can afford it, I HIGHLY recommend the G70... Two years of trouble-free gigging so far, a joy to play and listen to.
