I have a Supermax 25/50 and use it on almost every project - probably every project. If you want to avoid the cost of a wide belt sander, I'd recommend a wide, single drum sander. I had a 16/32 and often found that I was doing work wider than 16 - and the idea that you can do two passes and get 32 is a outright lie. It's just about impossible to get your drum sander adjusted so that you don't get a ridge between two passes like that.
But 25 inches has handled just about everything that I do.
