Wheel dollies, who has experience with them?

[Pitterpat]

So I have always said I should buy some but never do, I think I finally have a reason to. These will be used on the Caddy so that I can either fit all 4-1/2 vehicles in the garage (ya right) or just move it further over to gain some extra space. Anywho I found these on Amazon http://www.amazon.com/gp/product/B0...oliid=IRXRCW2JB4378&ref_=wl_it_dp_o_pC_nS_ttl and seem decently priced but I know nothing about them. Has anyone used this brand? Have a brand to recommend? I would like to stay around a $100 but depends if I will go up.

Well, I have 2 sets of wheel dollies my VW Bug sets on but you know it's a lot lighter than whatever you'll use them for. If it were me I'd buy the Go Jacks, because the other kind are just pans with wheels.
