File Manager

I need a file manager bad! I have tried Rage Macintosh Explorer but it is real slow and flakey. I also tried another who shall remain nameless for there horrible company practices. Am I stuck with finder? Finder is great but I need hierchy for my folders... I hate to say this but the layout of windows explorer is great! Its also flakey but great layout for managing lots of files. Most of what I need is to rename move delete and copy files from my NAS and family computers. It also wouldn't hurt to be light on resources. My MBP could handle it but it is also something I would like to use on my older 6000mhz iBook. Any help would be great!

Thank You

 

Well I tried MUCommander not what I had in mind. Any one have any ideas?
