Just been in the Tesco in Leeds (Seacroft) and they've got Black&Deckers version of the Dremell the RT650KA with the accessory kit included for £24!.
Used these for years with serious abuse and they seem to take it well so if anybody's consdering investing in such a thing keep your eyes peeled!

Just been to the tesco extra in cradley heath and they have these in stock but at £50.

Well if they offer price match I could scan the receipt for ya.. Or ive had the ring another branch and when they confirm the price they reduce theirs to match.
