Hi Jim, thanks for a brilliant link + details of the Contour HD camcorder/helmet cam, HD one around £315, not cheap, but reasonable for what you get and the thought that's gone into the design - flexibility and quality of product and results seem to be excellent. Just paid a bit less than that for a Uniden UBC800XLT (birthday present for myself - well, that's what I told my wife, to save her having to find something! It sort of worked.).
