I'd like to say that Bob 'N Ed (bobned.keenspace.com) was still one of the best webcomics out there, but it's time to accept that Al either hasn't the time or hasn't the ideas to keep new strips coming.
Shortpacked practically goes without saying on a toy board, but it is up there.
I'm also a fan of
The Order of the Stick. It's a gamer strip that's damned funny if you get the references. It made the jump recently from webcomic to published when Dragon magazine added them to their monthly content.
