Race number holder - group order or make them?

Hi guys,

Ages ago I had a thread looking for info on the pro style holders/brackets for race numbers. Anyway up until know I have been using a modified light holder which sometimes works and sometimes doesn't, which is on the seatpost which isn't ideal.

I have found where I can get them by now. Rotor make a race plate, a cheap aluminium which integrates into the rear brake mount, except shipping seems to be a killer for such an inexpensive part.
We're talking 20 quid from dulight.fr or probikeshop.com...or €14 from ebay.

I mean there are fancy carbon ones for a few grams less for €18 too on ebay.

However, I was just thinking would there be a demand out there if I or someone on here was to make a couple which would be very simple and just a couple of euro for postage etc? If not, or if people don't want to go down this route, would there be any interest in buying in a couple and saving on postage by splitting them when they arrive?

I don't mind trying to make myself one, or pay a once off 14 quid but would like to think of there was a demand we could all have them for less than a fiver? Let me know what ye think. Cheers!
