Not a fan of Rotarys, seem to have more problems that they are worth. Plus, it seems that when you do need parts for them, they aren't available or have been discontinued. I have heard that Rotary went out of business or went bankrupt.
Seems Bend-Pak is the popular brand, now.
Whatever you choose, make sure that you get one with sufficient capacity, bigger is better, and have it mounted securely. And as stated, as long as you get the lift ponts set right, they are very stable. Oh, and one moe thing, get one with enough lift hight that you can work comfortable under it. The ones I work with (Rotarys) don't really go high enough for me to get under, and I stand at 6'4".
