I have been using PHM until today, but I don't like using/supporting products with a stalled development cycle (especially stalled for 6 years). Not that PHM RegEdit needs a lot of improvements, but at least update some graphics to be more VGA friendly and call it 1.0 already considering the functionality is pretty solid.
I finally broke down and tried out
Total Commander today... I like it so far, although I'll be looking at some other alternatives too.
