The thing I like about Genie screw drive is you can buy an extension for doors taller than 7 ft. For the money, the Genie is the cheapest and they work well. Only problem is I can't reprogram the remote key pad.
The screw drives that Sears make looks like a Genie. The sears controls won't work on a Genie. Had a photo sensor go bad on a sears operator
Have a CHI chain drive. One of the rocker switches that gets tripped by an attachment on the chain has been having issues. I have to trip it manually to get the door to go down. Tried tightning chain, still screws up.
A power surge took the brain box out of the CHI. Replaced the brain box and put surge suppressors on all of my overhead doors. I have 9 operaters total.
Have two ranor chain drives. They are about 20 years old. Never gave the first problem with them.
My two older operators, CHI and ranor, have 10 dip swithes while the newer Sears and Genie have a floating code.
My 2005 buick has a place where I can program in the old 10 dip switch code, but not the floating code.
Hope this helps you decide what to buy.
