Used this place a few years back when I bought my current tractor. Not a recommendation of their service, just the one I used. Located just north in Bolingbrook. As for quality of service, my impression is that they are about equal to your typical dealer. So, on this forum that's not saying much. But, they have a dyno, not that it's gonna tell you much. Although, the dealer I bought my tractor from (House of Trucks, a Rush company) shipped it to this place for a Dyno test and DOT inspection and ended up spending a few grand on parts, so it wasn't all a waste.
