I beg to differ Lincoln.

That entire car was done with my Chicago Tools rotary. So yeah, if you don't want to invest a ton of money, then go with the Chicago tools rotary JUST to learn how to use one. Just make sure you invest in a quality rotary if you TRULY want to use one professionally. You can switch backing plates and such just like any other rotary and you might get lucky and get one for $29.99 like I did.
When I have the money, I will be buying a Makita, but at the time, I wanted to test out a rotary just to see if I even wanted one before I really invested $200+ into a quality rotary and it fit the bill. It's a little less powerful than the makita, but you can put plenty of pressure on it without slowing it, just if you smell something burning, you may want to let up on the pressure a bit as that would be the electricals being too stressed. Remember, it is NOT a Makita, so try not to treat it like one. The more you use it though, the better my Chicago Tools rotary seems to be. Anyway, good luck either way.
