Modern lights need so little power that you can power them with any dynamo hub. The more you spend, the less drag the hub has. I've been riding on Sanyo hubs for a few years. They are the cheapest and draggiest, and I don't mind, and they fully power my lights. It sounds like SP is the best compromise between performance and price.
Buy the fanciest headlight you can afford.
You'll be glad you did this.
