I bought a racing jack from Northern Tool for like $200. No problems at all. It's pretty light and I have no complaints. I was going to get a craftsman until I read about 5000 bad reviews on how much they suck. I didn't want to spend the Snap on/ Blue point kind of money so I went with Northern. No complaints.
