If you find it for 50 bucks you either are going to hand your money over to a scam artist, or a crook who is copying dsmlink. The price is on DSMlink.com, but there are also some versions sold on ebay for slightly cheaper from vendors who have been given permission to sell dsmlink.
Perhaps you meant Keydiver's chips, in which that would be
www.dsmchips.com . He makes eprom chip reflashes similar to DSMlink, with WAY less features, and they arent reprogrammable. However if you need something in a pinch, they are a good way to get a base tune layed down without effecting the timing map, you just simply wont have the ability to redo it down the road at will, you will have to send it back in and have another chip made.
