SCT versus random orbital sander?

I have the Eastwood SCT and love it. The machine is very well built and should serve me for a long time (I hope).
I used to use a 3M strip disc on a 7" buffer to scuff the paint and then paint stripper, but I like the SCT better.
The wheels are expensive but they seem to last a while and the option of using a narrow wheel lets me use the one tool in many places.
