I will try (at some point). I believe I tried compiling Python 2.x
with VS 2005 Express at some point, and it failed. However, that was
some time ago, and I may be misremembering. I will see if I can try
again, and report back.

Clearly, if VS Express *does* compile Python - particularly if the
"official" build matches an Express version (not true for 2.x at the
moment, it will be for 3.0) - then my concerns go away.

The biggest problem with 7.1 was that the free version (built from all
the pieces, as you say) doesn't support the project files used by the
commercial product. If the solution files in PCBuild8 and PCBuild9
work with the Express compilers, then that's the biggest hurdle I
encountered previously resolved.
