Angus Yes I did a fast check and couldn't find anyone in the US that seemed to carry it. The eval kit looks nice but will speculate its quite costly. That said I could see some uses for it like you say it has some things built in to eliminate false triggers and such. Just need to know if $1.59 or $159 each. Cheap chips I may play with. Regards Paul.
