I don't work for pharmacia but can say I've had good luck with the
sureclone kits they sell.  Not cheap, $225 for 25 rxns but once your sure
your blunt ended CIAP treated vector doesn't self ligate, don't do a
vector alone ligation control. 

If someone else can post another sure fire method, I'd love to try it and
switch to save some bucks but for now, I clone all my PCR products into
Sma cut pSP72 with sureclone.
