Mission Hill, maybe? It's on Youtube. Not really the same type of show as Bojack, but it's funny. Here's an amazon link to the DVD so you can see reviews of the series.
DVDs on amazon are your best bet. Worth it in my opinion. I got a copy like 15 years ago and the commentary alone is a large part of why it never got purged with most of my dvd collection years back. Idk if my link takes you to the selection properly or the $50 set, but there's options for the $20 range available. Well worth it as far as I'm concerned.
You can get the DVD set for under $25.
Iirc, MTV had Undergrads, another underrated animated TV show.
