Reflow PDF to read on my Kindle is my last resort, but since that is what you're asking for I'll list my process here.
TOOLS:
Mobipocet Creator 4.2,
BookCreator , and
Calibre (all are free tools)
1) Import the PDF to MobiCreator. This is probably one of the best PDF to HTML tools that I have tried and it is also free. The results is almost identical to the @kindle.com
2) Open the HTML file and copy and past it into BookCreator (BC)
3) Format the text to how I want it to look, add table of contents, and cover page.
4) Create a MOBI book.
With MobiCreator you don't need to use BC to create a TOC and cover page, but I use BC because it is possible to format the text where as in MobiCreator it would require modifying the HTML code, thus taking more time.
