Paragon looks pretty good, thanks! Does that program allow me to move files from NTFS to HFS, ("converting" those files) or will NTFS files remain NTFS and HFS will remain HFS? I was assuming that I would want to have everything HFS eventually, just since that's the native OS X system. Plus, then I might be able to use the 10 day trial of Paragon to switch the files without buying the whole thing.

If I took my PC to a Mac store (which is a ways from our house, which is why I'm trying to avoid that) and had them transfer my files, would they basically be using a program like Paragon to move files from my NTFS drives to the Mac's HFS?

Thanks again for all of the help with this! Trying to make sure I don't have too many headaches with the switchover...
