Great work Neil, I never heard of this place before
http://www.strikemodels.com/products/speed-controllers/ and reading the Blog area, the company just move to Washington, so that's just a short hop for you Reg.
I just phoned in my order for four Viper Marine 15 esc's, then they'll send me a PayPal invoice via email. They said they have them in stock & will be going out today.
