I have one, a Casadei 970 style speed sander.
If you have the room get a speed sander not a drum sander, much more effective both on removal and finish quality plus easy belt change.
Mines 970mm wide, fine for most items, the odd wardrobe frame need sanding before assembly.
Every thing goes through the speed sander, my most used machine, needs good extraction.
They do take up a lot of room, need 3m of clear space in front and behind.
Belts are about £13 each.
I make a kitchen every couple of weeks, we have 6 guys in the shop, size is fine.
Go for a reasonable brand, not Chinese cheapos.
