Positioning Jacks

[mssl72]

I was looking at car "positioning" jacks, wheel dollies, etc. Something setup like these:



I was wondering if the crowd had any recommendations, brands, things to avoid/consider/watch-out for. I don't want to spend a ton of money, but at the same time I don't want to cheap out. There seems to be a good amount available. I just don't know how good any of them are. The foot pump setup is handy since I'm up close to a wall on one side. Thoughts??

Thanks in advance!!
