I just replaced the explorer shell with this. It's very slick, and I like it better than litestep shell too. It's very nice to configure and mess about with.

Now I have less chance of explorer.exe crashing, but explorer.exe is still used for folder browsing, so does anybody know of a replacement file manager similar in style to explorer, but a bit less bloated and crashy?
edit: Explorer just crashed! wooo! At least my start menu and stuff doesn't disappear anymore when that happens!
