Thanks for the information Lu.
BTW, I knew where the shop was but their prices are so high I didn't feel like doing anything which might help their sales.
You say you have their price list. Just as a matter of interest, how do their prices compare with those in the US/Canada for the same models?
The problem with UK prices generally is that 'you get what you pay for' only relative to other UK prices. Most things are £ for $ or worse, compared with US prices.
