PTC II upgrade
I hate to appear cheap, but I would like to upgrade to PIII and find I need to modify my controller so it will generate an electronic key. I understand that this will require installing a circuit board. Farallon says they will do it for $100 plus shipping. In fact, they will do the whole upgrade to PIII for me for $300. That seems awfully steep. Is there any other way to upgrade? Is the circuit board available anyplace?
Thanks for the help
