Hi Jugster,
I found dealing with CS-Labs directly to be great. Emailed them asking for a quote. Received a reply within 24 hours. Paypal'd money and items dispatched 2 days after that. Quick delivery. Had only 1 hurdle with prox sensors and emailed them on a Monday night and had a reply Wednesday night, sorting it out. I'm in Australia. So US shouldn't be a problem. If you like I can PM you the sales and marketing managers details.
