I found out about these on another forum and thought I would share the link here. http://www.bicygnals.com
I ordered up a setup to try it out and it came to a reasonable $72 or so shipped from across the pond. In the grand scheme of things that price doesn't seem that bad. Especially after walking the aisles of Interbike recently looking for just this type of product and not finding it or anything like it. I did see some other stuff though that cost alot more that didn't do much for me however. The one that sticks in my mind was this one: http://www.thesirlight.com/ which retails for $99 and is about useless in my book.
When I get it I will report back here with the results.
