I guess I'll be the other side of the argument here... I have an edge comp and I've had to send it in twice to be repaired. It'll stick at one power level and leave it inoperable at times. However, they have fixed it both times which I've had to pay only shipping ($5 each time I think..) It started doing it to me again so I just turned it off and haven't turned it on in about 8 months. Also, I have a VP that adds timing by itself so running the edge (without controllable timing) puts too much timing on at once. It's kinda like stacking two timing boxes. BAD. Anyways, I haven't ever tried an adrenaline, but I'm not that impressed with my comp which I paid $629 for. I could have done better.
