I have an Ebay $29. rotary. I use it 2 or 3 times a year on two different cars. The only feature I would like added is the "constant RPM control". I dont know what it is called in tool terms but it keeps the RPMs of the buffer the same, even under load.
As stated before, unless you get a powerfull orbital you might as well do it by hand.
The rotary is not hard to learn. A lot of reading & a little common sense and patience will pay big rewards. Doing the work slowly at low RPMs will not cause problems useing the proper pads & products.
I've got four times or more of the cost of the rotary in the pads & products so no matter what you do it isnt gonna be "low cost".
