I'd like to suggest a TA cloning vector from Novagen that I have been using
with great success called T7-blue. You need only buy the vector which is 
priced reasonably (be careful of shipping costs...), they recommend
using "NovaBlue" competent cells, but it appears that XL1-Blue is an identical
E.coli strain and is what I had in the lab. A number of other labs here have
began using this vector as well and have been pleased with the results. 
Their phone number is 1-800-526-7319. I wish you good luck in your research.
