The
E-book Reader Matrix has a PDF Capabilities row. Look for "Single Page Reflow", which is what mobile ADE supports (at the vendor's option).
If your PDFs are similar to each other, I also suggest trying Calibre's PDF to ePub (say) conversion. You would probably have to fiddle with it initially, but it has the advantage of doing full document reflow and you may be able to do batch conversion once the PDF options are customized for your PDFs.
