Size-Fractionation of DNA

Before subclonning ds DNA generated by PCR into a plasmid, I would like to 
remove small DNA fragments.  The template used for PCR was a subtracted cDNA
library, so there are many different sized fragments present.  One method
that I am aware of is to use a sepharose CL-4B column.  Have others used this
method with success?  Are there other methods that are simple, but still give
good recovery?  Thank you.
