A better command line for Windows?

cmd.exe on Windows sucks. Cygwin and MinGW aren’t really Windows (though they are certainly better and cygwin is what I use). So, I ask the lazyweb: is there a better command line for Windows? It looks like the company that made 4DOS (JPSoft) is still around and makes better command lines. They’re not entirely cheap though. Are there any free choices?

Seems like this would be a good Python project, given the tools for making Python command prompts and the excellent Windows integration that’s available.
