Looks like they've released a new CAN controller - SD540C. Good pricing too and integrable with a network of SRXs.

Re: Where to purchase wire?
Welding cable has worked really well for us this past off season, so +1 agreed. As far as the 12awg wire, looks like we'll be purchasing from powerwerx and trying out 45amp connectors.

Re: CalGames 2016
When you say that the pits are 8x9, is that 8 feet depth or 8 feet width facing the pit from the front? It might determine which shelves we bring - that is why I ask such an odd question :)
Thanks!
