Wow! Thanks a lot for this, Tom! Your list is a lifesaver for the inexperienced, not to mention the inverterate Ebay shopper. <grin>

Open Office works, is Free and Open Source Software (FOSS), though they may want you to "register". It's a vast improvement over any "Works", runs on almost any platform, and the price is right.

OpenOffice registration is optional. It's all I use. Supported my Sun Microsystems and IBM, and totally free. Transparency to Microsoft Office is quite high. It's pretty hard to tell if you are working in one or the other.

I have much later versions. Send me a PM with your personal email and I'll send you the very latest version.
I, too, recommend openoffice.org, even though you can get a free Excel reader on the MS site.
