Hey Jayrob. Do you make custom heatsinks to ANy host? I was looking at these (below) hosts off of DX, which are all MXDL's.I am going to use it for a 100ma BR host, powered by the 3.7v AA (or depending on the host, 3 AAA's) Let me know if you can, and what the price will be, since they have a MUCH smaller diameter for the sink. Below are the one of interest to me.
