Thanks. Very interesting. It'd be fun some day (this is pure fantasy) to have a show-down of the three formats (idler included). Everyone bring their tweaked, DIY examples, categorize them by some leveling criteria (price?) and let it rip. Of course, we'd have to hire enough security to keep things peaceful, but it'd be a hoot to hear the show. And congrats for nurturing a most entertaining and educational thread.
