Can anyone tell me the difference between the $50 version, and the $100 version? By looking at the pictures of them, I cant really see much of a difference.

Im cheap...I have the $50 one...I havent ever shot the other ones but I can tell you, Ive never had any problems with it. Its an excellent rest

I have the $50 version and love it. No problems with it. The more expensive ones have the lock down technology (which is supposed to lock the launcher down onthe shot preventing any bounce back, however, I've never had any problems with bounce back with the cheaper rest). The more expensive ones are also constructed a little bit more solid, and they do come with a LIFETIME warranty. The cheaper one does not. The best way to tell is check out their website. http://www.qadinc.com/

just 50$ is all!!

$50-PLAIN DROP AWAY, DOES NOT HAVE LOCK DOWN FEATURE, $100 VERSION DOES. THE HD MODEL IS THE SAME AS THE LD MODEL WITH AN DAMPENER BUILT IN. I HAVE TWO HD MODELS, LOVE THEM...GREAT CUSTOMER SERVICE...IF IT FAILS THEY WILL SEND YOU ONE THE SAME DAY, AS LONG AS YOU MAIL YOUR OLD ONE BACK. THEY HAVE A GOOD VIDEO ON THERE SITE OF IT IN ACTION. I PERSONALLY HAVEN'T USED A BETTER REST....DID I MENTION A LIFETIME WARRANTY.

I also use the $50 model and love it, have had it three years now and on two different bows. The more exensive ones have more precise adjustments too, more ways to fiddle with them. I honestly don't think you would notice the difference in the two though.
