dear loryn, 
you can prepare your own ta vector using preferably a vector containing 
Eco RV site.after the blunt ending,incubate the restricted dna with Taq 
polymerase and dTTP at 72oC for about 2 hours and clean them as normal dna.
there was an article regarding this procedure in Nature of either May,Jun 
or July 1994.If you can't locate it E-mail me and i'lltry to search for you.
I've tried it and it works as good as the commercial ones.
Happy trying!
