Try the zero-blunt cloning kit from invitrogen and you will 
never have a problem again provided the following:

1.  Generate your PCR amplicon with Klentaq (Clontech).

2.  Resolve your amplicons on a regular agarose gel (1% TAE       	
LE agarose gel, LE agarose is available from FMC corp.)

3. Purify your amplicon from the agarose with the qiaquick 
spin column protocols for agarose gel extraction (Qiagen).
Use 10 mM Tris, pH 8.3 for the elution NO EDTA

4.  Ligate the PCR products as described into the zero-blunt 
vector as specified by the manufacturer.  

5.  It always helps to EtOH ppt the eluted amplicon with 
5-20 ug of glycogen followed by resuspension in 10 ul of 
ddH2O, use 7 ul in the ligation reaction.

good luck,
