Diode Dynamics. They're a great vendor @
Diode Dynamics, and participate on these forums regularly. Shipping takes exactly one week, and I've never been charged duty/taxes.
Their customer service also goes above and beyond normal standards. Any problems I have had been dealt with swiftly, and always in my favour. Their kits also come standard with a water proof relay. They really do employ the "customer is always right", and are very helpful when you have questions regarding any of their products.
I
highly recommend them.
