I have been asked to teach an extra course this summer. I was thinking about perhaps buying a drum sander with the extra pay.
My issue is my limited space in the shop. I know the mantra is bigger is better, but I do need to still be able to maneuver in my shop.

I have been looking at the Supermax sanders

I like that the 16-32 has the quick height change and comes with the digital readout. Will I regret going with the smaller unit over the bigger ones like the 19-38?
I know I won't be able to do large table tops (or just make the rough center a design feature ) Are there enough other applications to justify the sander?
