Yeah I like the aluminum floor jacks. They seem to be coming down in price and you can lift one around without throwing your back out. I don't know about you guys but there always seems to be an air hose/extension cord/pile of crap between me and the vehicle I need to work on, so I often have to pick the jack up to get it where I need it.

Don't the aluminum ones only take a couple of pumps to raise also? My only concern is if it lifts high enough for a lifted vehicle. I know that they make special jacks for this purpose as well.
