Get the Hi-Lift brand jack.  When using pipe wrenches there is Ridgid and all the other stuff.  Hi-Lift jacks are like that. I'm partial to about anything US made and the factory is in Bloomfield, Indiana, about an hour drive from here.   They make an all cast version and a cast and steel version.  I'd recommend not skimping and getting the all cast version.

You can actually buy them on Amazon for less than direct from the company via ebay!
