It looks like cheapbytes doesn't sell Debian with the source disks. The full debian package with source included is 4 CDs and they only sell the first 2, which means the base install and the Debian archive of "deb" files. But Debian's site has a whole list of folks who sell the CDs (including cheapbytes) and there are others who do sell the source disks for still really cheap.
The thing to be careful about with these guys who sell the disks (often on CDR) seems to be to watch out for what they want you to pay for shipping. Some of them will sell you a CD for $2 and then charge you $10 for shipping (via regular US mail!). That's just plain dishonest, and I'd rather they tell me the truth... charge me $10 for the software and $2 for the postage. I won't give money to people who start off by lying to me.
In the Good News section of developments... I got my books yesterday. I bought O'Reilly's "Running Linux" and "Linux in a Nutshell" but delivery was delayed and I'd been waiting. Now that I've got them, I wholeheartedly recommend the "Running Linux" book to anyone who wants to set up Linux. It's in English. I can understand it. And if I'd had it before I started with all of this I would easily have avoided a lot of the pits I've fallen into. It's already cleared up a lot of things for me, and I've barely even started into it. The "Nutshell" book will, I think, sit on the bookshelf for a while because the nutshell books are intended as resource books for folks who already have a clue, but it will eventually come in handy. But if you want to install Linux and you don't know what it's all about, get the "Running Linux" book. Good stuff.
