Here's a nice convenience site that reduces the amount of time you need to search around redhat.com or mandrake.com just to download ISO CD images: LinuxISO.org. Many distributions (including some BSD distros as well) are there, ready for downloading, plus pages to help newbies with burning and such. I haven't tested their bandwidth 'cause I just recently downloaded Mandrake 8.2 images from an official Mandrake mirror.
