tetons9,
my advise to you is don't try and save a few bucks by going with something cheaper. I have used a verity of turbines and can tell you I wish I started with something that was more expensive but worked. I like you (if you go with a cheaper turbine) purchased a turbine that was lower priced and promised to out perform everything else on the market. Well I had nothing but problems, I wanted to fly not screw around with constantly calling the manufacture for help, and sending the turbine back for a fix.
Take it from me and learn from my mistakes, if you want to fuel and fly go with something that really works!
