I like em! The pair in Omega have been in there for a year, and before that were in Alpha for 3 years, and i thrashed them! Apart from a couple of relays ive had to swap theyve never let me down. They only reason i upgraded to the Vantec was for the bigger motors. I personally rate the 15amp CPU version over any of the other electronize (inc. the 30amp ones). Of course Vantecs and sidewinders are going to give better performance but you get what you pay for, and the Electronize seem to better than most in its price range.
