I'd absolutely buy it!
About a year ago, I suddenly got the urge to watch it again to see if it was as funny as it was when I was a kid. I found a few episodes on YouTube, so I watched them-- as it turns out, it's even better than I remembered! I was laughing my ass off the entire time I was watching it!
It should be on DVD, but I doubt that it will ever be released on any medium other than the few VHS copies that NIckelodeon released while the show was still on the air. It's a shame that the show has kind of faded into obscurity. It was a great show with a surprisingly mature sense of humor.
I miss it so much!
