IMO, getting anything from TJ is a bad idea. First off, most of the gear sold in the border towns are fake. Secondly, trying to smuggle gear back in from Mexico is a really bad idea. Either customs will find it or the Mex police will snag you. I don't think you want to do any time in a Mex prison. They have people in the pharmacies that are looking for dumb americans wanting gear and reporting to them. So if you don't go to jail, you will probably be taken for everything you have. Not worth the risk my friend.
