Welcome to the boards! You were steered correctly on the MKIII, there is no better place. Try not to take constructive criticism too personally, it's gonna happen. As I witnessed in your "Need some Help" thread, you have some of the best help you can get there already. Either follow their advise, or go your own way, and don't comment on it. But, I'm betting you'll be sorry if you don't take the advise. If they advise something that is over your head.....don't be afraid to ask. That's not to doubt you at all, just a little advise.
We'd like to see you stick around. With 3 MKIII's built, I'm sure you have information worth sharing.
