Need a suggestion on some Bodywork Tools

Im a cheap **** so I buy one of these-View attachment 151779 and knock the arbor out and mount on my grinder, you get two wheels for the price of one. You can get these at sears, HDepot, Ace etc...

These things work great!

You could just save up and pay a professional to do it (the hard stuff that requires the specialty body tools)... I know - but wheres the fun in that.
