Since Mark has a variety of implements (and manufacturers) listed in his signature line, I suggest his best bet would be the Pat's Easy Change. As we all know, the most difficult part of hooking up any implement is the lower (draft) links. Pat's accomodates that quite well...especially with a spreader bar to hold those lower links in position.
Since Mark wrote "Money's not really the issue, ease of operation is.", he may be willing to modify any implements that would require modification to work with a Quick Hitch. That's his choice..and I suspect at least some of those implements would require the modifications.
Of course, he'll still have to get off the seat to hook up the PTO driveshaft...
