I would contact Thunderdan from here on OSO. He deals in Active Thunders. I would also follow Troutly's advice and look into Formula. They do take big power to go really fast, but they build an absolutely beautiful overall package and follow up is even better. You can tour the plant and everything. I hear that Magicfloat from OSO is excellent to deal with although I do not know him personally, but the raves he gets on here are awesome.
