@The Rover I see that they're £157 with hrm now at wiggle. Buggerndamnation I couldn't get that past woman without a major drama.
I got a bit giddy then but still £194 when I check with wiggle and a bit more with the hrm.
I've been watching a few on eBay and they seem to go for silly money. Another £20-30 and people could be getting new ones!
