Like all things about Linux, even the help and support can be found for free. Linux HowTo's are free http://www.linux-howto.com , and there are always mailing lists when you need to ask questions.For first time Linux users, I will always recommand RedHat or Mandrake. Slackware is good, but unless the newbie Linux users is very intelligent or just has a couple of weeks with nothing to do, they will have a bad experience with Linux. It's like AOL. I'll bet that most of us here have used AOL at some point. But then we learned, we grew up, and we moved on to better ISPs. Same thing with Linux. For your casual user, RedHat and Mandrake are good because you don't have to be hacking files every day to make your system work. Slackware, Debian, and others are better for learning how a Linux system works. But a LinuxFromScratch system will REALLY let you know how a Linux system works.
Anyway, download the ISO's for RedHat and for Mandrake. I say this because you can try them for free and find the support for free as well. Then, once you find a distro you like, you can buy the retail to help support them.
