I just bought a Mac today ($250 for a G4 with 17" monitor - I couldn't say no <g>). Going to the Apple Developer site, I found that the latest Xcode is 2.1, which is for Mac OS 10.4, as is the earlier 2.0 (I have 10.3). It took a little search, but I was able to find Xcode 1.5 which is for 10.3.

1.5 still looks to be available on the Developer Connection Member Site. After logging in, select "Developer Tools" in the "Downloads" frame at the right, then scroll about halfway down the page until you see "Xcode Tools v1.5" (372.4 MB).
