Phoenix (and all others interested in Linux),
If you want to get the latest stable releases (cheaply!) of most of the Linux distributions, visit
http://cart.cheapbytes.com/cgi-bin/cart. They have good prices, ship quickly, and are pretty reliable. However, if you want the source to a particular distro, make sure it says that it is included. Otherwise, you are likely to get a binary installation (which, as Phoenix pointed out, may cause you problems down the road.).
Enjoy!
Matt
