Thanks for all your comments.
As with many other applications, there are always freeware alternatives that can do as good a job or a better job than the commercial choices. I understand there are also commercial applications that are best of breed and no free programs would be able to touch them. I just wanted to see if there was anything free that would equal Lightroom. With all software, I always check for freeware alternatives first. I've looked for a freeware alternative to MS Office but don't feel comfortable with anything but MS Office and purchased that. On the other hand I have other freeware applications that meet my needs just fine. If there is no quality alternative to Lightroom then I will go with Lightroom. I don't mind spending money where needed but why spend money if there is no need to? I appreciate all the reasons people listed why Lightroom beats all the alternatives I asked about. I don't need to be told I'm just cheap...I wish I had the money for the same equipment some of you have but I make do with what I have and see it as a challenge to get the best out of that.
My original concern was not only about price but computer resource usage also. I've read concerns other people had about how slow Lightroom ran on their computers and wanted to also see if anything else would be more efficient with computer resources.
