I have a new 3320 I bought this fall. The I-match listed for $244 but got it for about 15% off that when I bought it as a package deal. The I-match works on my MX-6, JD weight box and Frontier blade. I am interested in a finish mower but everything I have seen is not compatable with the I-match. Even the Frontier rear finish mowers require a conversion kit that will set you hand a couple hundred.
