Ow! Given the current exchange rate...

Disclaimer: I have no information, and I am just guessing...

If it is available through the RioStore, I think a good estimate would be to take today's published MSRP of $350 (rounding), convert that to GBP (using today's exchange rate from CNNfn) to get about £206. Rounding up a little further for general purpose, I would guess that it would sell for about £210. Perhaps there might be a "street price" of £199.

Remember, this is only a guess.
