Just googling "genealogy poland" gave me a bunch of sites that aren't Ancestry.com. Not all of them were helpful, but they might help you. There are still some free sites out there like genforum and polishroots.org. It's not all in one location - you do have to do more legwork (or is it "finger work"? ) - but there are good sites left. I found a ton of info at usgenweb.org too.
I finally located all the floppy disks that had my Family Tree Maker backups on them. Now I have to burn them onto disk and load them onto my laptop. Crossing my fingers that the floppies are okay!
