Considering the purchase of a drum sander. Every performance report on the Performax and the Delta seem 50 -50. Are they really that high maintainence of a tool or am I just reading reviews from folks with a low tolerance for learning curves. I like the reviews on the Wodmaster but I can't justify two grand and 560 pounds on a drum sander. Does anyone know what brand David Marks uses in his shop? Any feedback would be appreciated.

Thanks
Dan
