I am thinking of purchasing a larger pro type sander (25" width) and the drum sanders are obviously more attractively priced than the wide belt sanders.
I understand that the wide belts allow you to run for longer periods of time due to the longer belt (less material buildup and overheating problems).
If you were using this sander for say one continuous hour at a time, would the drum sanders have problems with overheating of their head(s)? This would be used as a finish sander and not an abrasive planer :-)
