digestion of PCR product can be very tricky, what i do is following:
1 purify your PCR product with qiagen kit
2 use T4 PNK phosphorylate your PCR product's blunt end
3 ligate your blunt PCR fragment into any vector cutted with blunt end enzyme
(like EcoRV)
4 transformation and mini prep plasmid
5 then use hindIII and EcoRI cut the fragment out of vector
6 purify your hindIII-EcoRI fragment with kit and insert it into the vector
you want to use
this will add one more subcloning step but i am sur
