where to buy one? Good as backup as i got a lot of SD but 1 CF card
I might eventually give this a try together with a Eye-Fi card.
If only eyeFi makes CF cards too.. with more real estate maybe it'll be cheaper or have better performance/capability..
Yes, it is available in UK as far as I know but of course people should be able to get it from online stores such as Amazon http://www.amazon.com/Eye-Fi-Share-Video-Memory-EYE-FI-4SV/dp/B001U0O5QE/ref=pd_bxgy_misc_img_b

using CF Card Adapter with Eye-fi wifi card is not that straight forward, first thing Eye-fi does not recommend doing that.
second thing the effective range reduced..
third thing is not all cameras compatible, eg Nikon D700 does not work well..
