Acoustic Guitar Construction

I've been thinking about buying a benchtop oscillating spindle sander. Grizzly has a few on sale for under $200, but I don't know exactly what makes on better than another. For a small-shop low production guy, what should I be looking for or what should I avoid?
Thanks

Ha ha - you just got the Grizzly flyer. I was looking at mine today and that was the one thing i wanted to get. Someone told me the HF one was decent as well. But not sure what makes one better than another.

EDIT PS - that was me with the cam clamps but they're gone.

I would almost go for the rigid oscillating spindle/belt sander instead, get both for one. I have the HF, works great, but could use a better belt sander than the floor sander mounted to my bench.
