Hey there and welcome. I'm afraid you have asked the noobiest question of all noobs and you seem to have revived a couple of sarcastic comments back.
In a few weeks you will know why, you will look back and smile, you may even drop a couple on the next noob.
I would go with TC. As you read more you may disc over Frankens. I did and I'm sad to say an out of the box rep doesn't cut the mustard for me anymore. Damn those genuine parts!
Anyway the Tc sub pops up regular now on the sales forum. They accept gen parts, quickest mod is to stick in a gen insert and this thing is really good to go. Good luck.
Here's mine with gen insert and crystal.
