The small Harbor Freight 1.5 ton aluminum low profile jacks are probably on sale for around $70 right now but if you don't want to drive to Harbor Freight and deal with the lines at the register I found them on ebay for $79 shipped.
They look and work good and the price is great.
Check tightness on all the bolts and grease the moving parts and they last.
1 5 Ton Compact Aluminum Racing Floor Jack with Rapid Pump® Pit Crew Quality | eBay
I have the bigger heavier grey 2.5 ton low profile steel floor jack someone posted above and I like it too.
This small aluminum one is nice. You can easily carry it by the handle one handed or in the car on a trip. Sometimes you need two floor jacks.
