I say go for it. The 11R is a fantastic unit and you do get a lot for your money. As I said, no regrets from me and I doubt you ever will regret buying one either.
I feel that I've outgrown it but will keep one of them 'for ol times sake'.
The only reason I can actually afford and AxeIII is I have a vehicle surplus to requirement....lol that sounds crazy, selling a car to buy a piece of kit.
