I fully understand.
Draw up the schematic for it, pics, parts used, etc - send it to me. I'll get it to my guys and we can see about sending it overseas.
Put it this way........a part that was normally $20 I thought I was doing great to get at $13......it was $4 in China. Adds up a LOT when my first run of the adapters was 115 sets.......second run was 100 sets, and I ordered another 85 sets today.
