Why spend money on a family tree maker when you can get one for FREE???
Everyone loves something for free... don't you? It boggles my mind why people would want to pay for one when there's alot around for free, and some excellent cheap ones. Here's a list of the best free family tree makers I know of.
http://www.myheritage.com/page/free-family-tree-maker
http://www.legacyfamilytree.com/DownloadLegacy.asp - (Standard version is free)
http://www.genopro.com/family-tree-software/ - (Free working demo)
http://www.vertigo.com/familyshow.aspx - (You have to download .NET FRAMEWORK 3.5 first, still very worth it, excellent free program. Source code available too!)
These seem to be the best 4. I may have missed some good ones so please contact me if you know of any other free family tree makers.
