It's free, no frills, candy or nags (as at Oct 4 2014) - I also like it because of its name

+1 to both BullZIP and PrimoPDF.
I've used PrimoPDF for many years on Windows OSs since Win2000 and WinME and used BullZIP for the past year or so on Win8.0 & 8.1. Both are excellent.
Using a PDF virtual printer is a good tool for "flattening" complex PDFs. Simply open the PDF in Adobe Reader or whatever "big" PDF reader you use and then print to disk using PrimoPDF or BullZIO. The output from either of these is often much more palatable to eBook readers.
This is/was an ancient thread but if I were in the OP's position I would first try converting each PDF to EPUB individually and then merging the EPUBs. That way you can use different "magical incantations" for each conversion of the PDFs as each individual file requires. The merged EPUB could then be used as the master for converting to the desired final eBook format (e.g. Kindle, ...)
