I use the Muzzy Zero Effect and love it. It is difficult to put together the first time but I feel that I could put one in much faster than a day now! It has quite a few moving parts, but I havn't had any problems. I have also shot with a Trophy Taker and liked that as well. I do like how the Muzzy guides you arrow into place without fail every time, I havn't shot with the Trophy Taker enough to give an expert opinion, but could possible see this as being an issue. One rest that I would stay away from is the Trap Door. I've shot with this rest also, it made quite a bit of noise from the recoil of the springs when it falls away, I have also heard a couple of stories of it sticking and not falling away at all. As always these are my opinions and might not be everyone's. I was in the same boat as you a few months ago trying to make the same decision. I havn't regreted the Muzzy yet. Good Luck!
