Has anyone here used a company called spark and fuel to purchase a pre-assembled MS setup? I am thinking of using the MS instead ofa the e-manage to satisfy my fuel and management needs and don't want to spend the time trying to solder and put it together. Their site looks decent, but I have heard of MS ripoffs like Mr Slick here on the board so I want to go to a legit outfit. The website is www.sparkandfuel.com, although their prices look somewhat high to me.
