ECU flash help

I was wondering what every ones opinion was on who I would be better off going to for the ecu flash. Pretty much I am trying to decide between Al at Dynoflash, and Turbotrix Racing. I have spoken with TT on the phone, and I really liked their customer service, and the fact that they will flash my ecu for free every time I upgrade, all I have to do is cover shipping. But on the other hand, Al has the new option of the two step launch control. Any insight is greatly appreciated. Thanks in advance.
