Agreed Jimbo. They often have stuff much cheaper than computer shops.
Also worth a look are ALDI and LDL.
I got a graphics slate from ALDI for £14.99. Came home and Googled it and the cheapest I could find (same brand) was £40.
ALDI normally have one cheap "major" electrical device on offer all the time. These have been laptops, large LCD tvs and power tools in the past.
Well worth looking in basically, cheers, John
