I don't know that this was the Dremel that I tried. My only experience with a Dremel was not pretty. I opened it up, used it for a very short time, boxed it back up and returned it to the store. It had a TREMENDOUS amount of vibration. May have had other things I didn't like, but I've slept way too many times to remember.
They do make one with a sanding station on the side. I have no personal experience with it, but know one of the guys at the Greenville WC that likes it.
If you are going to use it occasionally it may be fine. If you are going to use it to really scroll saw much, you might want to look at other saws.
