Is your shop in New Hampshire?
Mine is and they talked me into the cavalier rest. I shot it about 3 months with no problems. I think it is a quality rest. But, I also wanted a DZ and found I kept questioning why I bought the cavalier. Long story short I got the drop zone off eBay. It took about 20 minutes to set up (hardest part was tying into the buss cable). I tinkered with it for 10 or 20 shots while paper tuning and I have fallen in love. This rest is quiet, smooth on the draw and performes flawlessly. After spening roughly 50$ on the cavalier and then almost another 100$ on the DZ I can say I'm satisfied.
I'm sure you'd like the cavalier as there is nothing wrong with the rest but if your heart is with the drop zone don't cheat yourself. You'll regret as I did and end up with the DZ anyways.
