I am not a big believer in the fuzzy logic myself. The solenoid technology seems to be the way to go. You should have 0 problems with the SBC-iD. I sure don't. :-) As far as version 1 or version 2, it doesn't really matter. They are practically the same as far as I can tell other than the screen color and the buttons being chrome on the second version. They will perform equally well.
