making concatmers of PCR products

[Morris F. Manolson]

Dear netters,  I have heard reports of people first 
making concatmers of PCR products
to improve the cutting of the PCR product with restriction enzymes
prior to ligating into the vector of choice.  I have also heard 
(or think that I have heard) that people are just throwing in 
some ligase after PCR (no fill-in, no nothing) and that this
is enough for forming concatmers.  Is this true?  I would appreciate
any and all protocols for making concatmers of PCR products.
I will of course post a summary at the end.  Thanks in
advance.  Morrie (boy, I am getting sick of PCR) Manolson
