Like Lovetone, I am also sponsored by PLANET, so obviously I am going to praise the mighty EGO. I have had the pleasure of hand bulding ETEK's at PLANET and I think they "ROCK!"
I personally like the way you programme it through the grip with coloured lights instead of the lcd display. I think sometimes too much information on a screen can confuse SOME people. If you put a setting in to the grip and it doesn't like it, it wont accept it.
If you are that unsure, I would say go along to a tournament and try the 05 and 06 out, if you cant get to the NQ, keep your eyes open for an ETEK.
If your ever near an NSPL event come and find me, you are welcome to have a go on mine.
