Hi Bud!
Here is some additional information.
Mac OS X Versions 10.1, 10.2, 10.3, 10.4, and 10.5, are complete system upgrades that must be purchased.
Once an OS has been installed, the point upgrades, such as 10.1.x to 10.1.5 (Final) 10.2.x to 10.2.8 (Final), 10.3.x to 10.3.9 (Final), and 10.4.x to 10.4.10 (Pending), can be downloaded for free.
Panther 10.3.x, and
Tiger 10.4.x, are no longer available directly from the
Apple Online Store, as
Leopard 10.5.x, is the most up to date OS.
But, if you know what to look for, a
Full Retail Version, of the
Panther Install CDs, or a
Full Retail Version, of the
Tiger Install DVD, can be purchased, sometimes less expensively, at some online Apple retailers, Amazon, eBay,
FastMac,
HardCore Mac, etc.
As
Texas Mac Man(Tom) posted, be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
Panther is only on CDs, not DVDs.
The discs should look
exactly like the images in the above links, and not say
Upgrade,
CPU Drop-in DVD, or
"This software is part of a hardware bundle purchase - not to be sold seperately." on them.

Once
Panther 10.3.x is installed, you can use the
10.3.9 Combo Update, to upgrade to the final version.
If your Mac meets the
Tiger System Requirements, you could also consider installing that, and then use the
PPC 10.4.10 Combo Update, to upgrade to the current version.
Additionally,
Tiger 10.4.x ships on a DVD, so if your Mac doesn’t have a built-in DVD-ROM player, you will have to use an alternative method of installation.
