I know many people have asked about them or have gotten a dental camera, but I noticed this one amongst others in an "ebay store".

Don't know if anyone else knew of them!

there are many articles on web exaplaining how to bild such "flashes"

http://www.virusphoto.com/12713-fabriquer-un-vrai-flash-macro-a-led.html

i believe it can provide good results, but you must use high light leds, not "usual" leds.
