Which brand of hydraulic jack do you have?

Sears has a few low profile ones on sale atm, and I'm looking to see if anyone has one or what other brand they'd recommend.

The reviews on Sear's website were mixed. Some attributed the piston failure to a crappy product, while others said it was owner error.

So, what brand do you have and how has it been holding up for you?
 
I am using a Roush one I got from Sams. It works great, lifts high, fits under my car (barely) ... I also have a truck though and need something that will lift more than 20in. The jack I have, while it works great, is not something you are going to transport around with you .. lol ... It weighs a LOT!!!!
