I have been looking at Advantagelifts.us and wildfirelifts.com.
As far as certified by ALI, I can't find the criteria but from reading the BendPak page that compares their lifts to Backyard Buddy it eludes that the BYB the cable is not tucked away where the BendPak is (as one reason that it cannot get ALI certification). To me would nice to have the cables tucked away but not necessary.
I like the squire tube approach of Advantagelifts.us, large 12" footprint.
Note that for 2016 Advantagelifts.us also incorporated a slack cable safety feature. I don't think BYB or Wildfire have that, Bendpak I think does.
Also Advantagelifts and Wildfire have cable keeper to ensure the cables don't come off the pulleys if slack is encountered. I did not see that on the BendPak.
If I can squeeze it in my garage, I think I am going to get the Advantagelifts lift.
P.S. Advantagelifts gives you aluminum ramps where as wildfire are steel.
