I'm considering one of these (used). Anybody have any experience with 'em? I'm wondering what changes may have been made from 2001 until 2004 (if any). I know in 05 they added the 2/4wd switch and disc brakes... but as much as I like the 05s, I can't afford one. I'd prefer an 01-02 in the $3000-4000 range.
