Figure if you have a need for a QD mount that will repeat zero. If you do, there are several available, with Larue being liked by many. GG&G is another name that comes up.
If you don't need a QD, and your optic tends to stay on your weapon (as mine do), the YHM should work fine for you, though it won't win you as many cool points. The YHM costs much less ($35 vs $120), but in the big scheme of things, your decision should be based off your needs, not the price.
I've used the YHM riser before, and it works fine, but I can't give personal long term use as I don't like risers on my Eotech. I know a few other guys who have used them, and they have had no complaints, but they don't pull their optics on and off either. I would obviously recommend Loctite if you go with the YHM. I run a Larue mount that I'm very happy with also, but its for an Accupoint, not an Eotech.
