JRS,
From what I've seen of the iMatch, it's your basic "quick hitch" system. If you only plan to buy implements from your Deere dealer that are iMatch compatible, then go with it. But if you ever plan on buying any other brand, I'd stay with the telescoping links. I have the telescoping links and purchased a SpeeCo (sp.??) quick hitch. To this point, I have no implement (LP rotary cutter, LP box blade, LP tiller, KK rake, KK finish mower, KK HD blade) that will hook up to the quick hitch without modification. LandPride, who sells their own version of a quick hitch, even rates their implements as being "quick hitch" compatible or not. If the one implement you buy that isn't compatible with the iMatch is a 700+ lb. rear blade, you'll be real glad you've got the telescoping links.
