helmet cam

I have just aquired the bracket which fits to the fuel cap and films through the screen. Now, my problem is that my cam corder records straight on to disc. I have had a few attempts today at filming but it keeps going pear shaped and I am assuming it is because of the vibrations on the disc.
I have been looking for a place which sells the helmet cam type cameras, similar to Soulkiss' and Rictus'.
The only cheap sellers I can find seem to be in America.
Can anybody recomend a good supplier?????
