I'm not concerned about whats cheaper or easier to use. I'm concerned with the quality of the rolling these can offer. Which one is better? It seems like shops mostly use rollers if I'm not mistaken.

 

go with the eastwood fender roller, that thing looks like itll mess up all sorts of bodylines and such, the roller bolts to your hub, and has adjustments so you can slowly roll the lip, not one harsh clamping movement, if its extra, spend the extra and get the roller, used it on my old car, worked like a charm
