I just looked at the price of the GoJacks on ebay......you would have to have extra money that you had absolutely nothing better to do with to buy those. Lets face it, they are nice, pricey, sexy, will hold you project with no problem, and are pinkish....now look at the cheap *** harbor freight dollies, they are nice, not quite as sexy, will hold your project with no problem, and come painted in black.
My car sat on the cheapies for 5ish years, they did the job, my dads e-body has sat on the cheapies for 10 plus years and are doing the job just fine. So when people complain of the cheapies being not of the quality of the GoJacks, gotta ask yourself, will the cheapies do what ya need and could you use the extra money on your project? Lets face it, the car is just gonna be rolled around and the cheapies will do that just fine.
