I've been using one similar to that for a while. Now I'm gonna upgrade to the actual lift from harbor freight. I have a coupon to get it for $299 (normally $499) and I have a store local to me. My buddy from work swears by this lift.
This is the one I'm talking about.The one I bought was $199 before the 20% off - they only had the 2 at my location, the steel one and the aluminum one I purchased.
