Just so you know, the vast majority of people here will think you're a troll.
In this case, a "troll" is someone who is trying to be funny. They'll think you're making this all up for a laugh.
My strong recommendation is that you save up your money and do the christmas thing. You said you just got a road bike; ride that a lot. By christmas, you may have decided that you like your road bike better and would rather spend your money on upgrading that. If you still want the fixed gear, you'll have hopefully gained some more bicycling knowledge and will be better prepared to get the fixed gear that's right for you.
I hesitate to point you towards bikesdirect.com because you may jump the gun and waste your money on a bike that you won't ride 6 months from now, but that is always an option as well.

wait until Christmas and read stuff on this forum to help gain some knowledge. In the mean time, go learn to ride your bike on the street or something.
You're still growing though. It would really suck to have 2 bikes that in a year will probably be too small for you.
