Gentioo with a graphical installer?
 

If I use this to do a graphicall "stage 3 install" I can then emerge a "stage 1" afterwards right?

IMO doing a stage1 install while quite educational, does not really give you any significant advantage over stage 3 installs.
If you're planning to upgrade your packages often, chances are all your packages will eventually be compiled by yourself anyway, no need to waste time on stage1.

An interesting side note, on the Gentoo handbook where it says the pros and cons of stage3, one of the disadvantage is
:)

I am proud to say that I indeed do not have the time to sit down an do a stage 1.... or a text based install. I think that's kind of silly anyway. If not insane... and I'm crazy already... no need to push it.

But the emerge feature does download source and complie and whatnot doesn't it?

Genereally speaking yes, but with stage3 install you still use emerge to install softwares, only difference is that they're precompiled (ie using emerge -k).

Any way to make it non precompiled? From a stage 3 install?

Gentoo is supposed to be a CLI install, even stage 3. The difference between the stages has to do with how much of the system is precompiled, not whether it's a GUI install or not. I wouldn't bother with a third-party GUI install program, it's really not difficult.

I usually pick stage 2 because it gives you a good balance between optimizations, speed of setup, and choice of packages to install.

I have done it both ways and the handbook way is the best,with the graphical installer you still need to edit some important files and emerge some stuff so you don't save any time,plus have some stuff you have to change down the road that is left over from the installer,plus it is not as up to date as a fresh install.

Yea during the install you need to use emerge to install software packages, you will be able to either install precompiled ones on the CD or download and compile latest version from the internet.
The choice of packages is the same whether you're doing stage 1,2 or 3, the choice is yours, it won't force you to install KDE in stage3.
