Auto shifter ideas what's the best

Well as a former B&M ratchet owner...It wasn't nearly as bad as I thought it was. If I had it to do over I would have bought a Pro ratchet, and kept it. I had a quicksilver and since I race so much, wanted a mechanical reverse lockout. A cheetah is what I have now....not something I will buy a 2nd time.
You'll have to excuse me Johnny I grew up with all my cars being a standard 4 speed only. Auto's I have had was just been in the last 10 years so all really new to me on witch way to go.
