H try Axminster Power Tools Craft Sander it is both disc and belt. Ref No :- AC 125 BDS currently £99. 98np. Ive had one for years and is totally reliable. You can even sharpen knives, chislels, drills, touch up lathe tools etc on the belt.
I highly recommend it. Regards, Roger G, Nr Stafford. If you are this way call in and try it.
