Was the same for me. For a Total Commander replacement give Forklift a try. It's not quite the same, but pretty good. I'm pretty much not touching Finder at all any more.
still worth a mention. been using sublime text 2 since the early beta and bought it almost right away, it's that good. i've been a big notepad++ fun in the past, but since for some now i've been working on both osx and win, it had been a pain to switch between different editors. sublime text 2 is cross platform and supports all kind of extensions. cannot recommend it strongly enough.
