I am sure that Invitrogen is probably making their TA vector by first 
linearizing the polylinker with EcoR1 and then ligating an EcoR1 linker 
containing a T overhang.

		eg:    EcoR1 side
        			     5'	AATTCGGCTT  3'
					    GCCGA

Such a linker would be easy to make and fairly cheap since it is so 
short.  Unfortunately, I can't say that this method works as well in the 
lab as it does on paper because I am lazy and just buy the kit.
