I guess I am one the the few who has never had a problem putting on 3pt implements. I say this after many hours of practice. /forums/images/graemlins/grin.gif Actually it is very easy once you get your system down and I no longer have any problem putting on implements. However, my wife does have problems switching implements so a solution for that absolutely had to be found. I went out and measured all the implements and decided that matching them by welding and drilling them all to a single quick hitch would be a royal pain.
I opted for telescoping links. Deere sold them to me for about $210. I like them very much and my wife is able to swap implements without too much problem. Would the quick hitch be faster and easier? Yes, but only after much more expense. Telescoping links make the job much easier for a minimal investment. And the tele links are universal meaning each implements is equally easy/difficult to put on.
I think most people damage their links when they put the link in compression(pushing backward). Even the standard links will break way easier in reverse than going forward. I actually don't see how you can damage your links going forward(steel is strongest in tension) though I know some people do.
I did not mention that I decided against a quik hitch before I learned to weld. Now the quick hitch would be my option because i would be getting more shop time which is almost as much fun as tractor time. I like the shop time because my wife usually gets up before me and is out on "her tractor" working on her landscape projects. If I ever bought a backhoe home my wife would be on it at dawn and would only show up at the house for lunch and darkness. My job around here is simply the mechanic.
BTW, in this economy i would guess that Deere will contiunue to have incentives and maybe better ones.
