Cointaker has 3 x kits of LEDS for the RFM. (link below).
http://www.cointaker.com/category.sc?categoryId=37They want $163 plus postage for the complete LED set up.
I personally buy in bulk like Pinfan, and i dont buy kits as such. For one machine here n there, buy a kit, but with alot of machines, buy in bulk.
