I've been looking around for "Font Choosers", and here are the ones I've found so far. Some of the screenshots are from my site, at http://www.geocities.ws/thezipguy .
You can feel free to edit this page, and add more "Font Choosers", if you find another one. A screenshot would be great, especially for comparison of features.
Zipguy 2013-09-09 - Wow! it looks great on Windows (which I'm using). I added it to the list of "Font Choosers", and added a screen shot of it also. It does show the list of fonts, by the name of the font, IN that font!
It's my new favorite. Thanks a lot for pointing it out to me, MG.
Various versions of "Font Choosers":
The one above used to be my favorite, but that's because it looks so familiar to me, since I've been on Windows (now 7,) back when 3.0 came out.
But, it is Windows only! I don't know yet, if tclkit-8.6.0-win32.upx.exe has it too, I hope it does!
MG It's not Windows only - the command is there on Mac OS and Linux, too. The dialog just look different on each platform; Windows and Mac OS both have native versions, while Linux uses one written in Tcl (looking at the source, it seems to be Keith Vetter's dialog above).

And here is one more dialog:
