We often screen our mixed PCR products by cloning and restriction digest to 
identify clones of the right length followed by "T-tracking" - running sequencing 
gels of with just one base (traditionally a T track as back in the old days this 
gave a distinctive run of bands with M13mp7). This works best when the inserts 
are directionally cloned, or you can use one of the PCR primers used to generate 
the clones.
