I'm surprised you didn't find any hits in your search - maybe it was thrashed thoroughly in the previous incarnation of this board, but I do remember it being discussed a number of times.
The only types of quick hitches I personally know of are the SpeCo (or is it SpeeCo?) (also sold by Landpride under their name - at least they look identical), the Freedom Hitch, and the Delta Hitch.
I had a SpeCo hitch that I bought 7 or 8 years ago lying in the woods until I gave it away a few months ago. Some folks like them fine - their value to me is the going rate of scrap metal minus what it would cost me to transport it to the salvage yard. It would only work with 2 of the 5 implements I wanted to use it with, so it was far easier to do without it. I would suggest you look at one, measure the attachment points, and very carefully measure all of your implements. Especially take note of the fact that it has to have room to slide up vertically several inches to engage the pins. If it will work with your implements, you'll probably like it fine, of course, otherwise it's junk. Another thing you should think about is that there's a lot of slop with this hitch, so I wouldn't make any great plans to do any real fine grading or delicate operations with it.
The Delta Hitch is very similar to the Freedom Hitch, except that it costs more, so that puts it out of contention in my book.
That leaves the Freedom Hitch. It's more expensive than the SpeCo model, as you say. But if ever there were a case of getting what you pay for, I'd say the Freedom Hitch is it. Mine causes a sensation every place I go - any time there are folks around who have spent much time hooking up implements the hard way, they just stand and marvel over the ease of use. Frankly, I still feel pretty much that way every time I use it myself. Still, if you don't change implements often, or don't have the money, it's not worth it, is it? I wouldn't give mine up - I'll tell you that.
