I've been meaning to pick up the Costco low-profile jack for some time. I've used it at a buddy's shop many times and it's solid. Plus, you can't beat the Costco guarantee. I'm sure they'll gladly swap it out if you pick out a lemon that got thrashed in transit. I only wish Sears would take back the two Crapsmen jacks that failed in short order.
