Default Folder X is one of those tools you can't imagine doing without once you've used it. I found the upgrade price a lot easier to handle than the full price, though. While I do think it is worth it, $35 is a large chunk of change for many folks. Since Apple now makes us fork over $129 every year for OS upgrades, and every developer seems to be nickle-and-diming us to death, bargains are getting harder and harder to find. I am glad to support good developers of terrific software (like DFX) but the higher shareware (and commercialware) is priced, the more people are encouraged to resort to piracy.
