Underpicked isn't really the same thing as being ineffective as a jungler. Mundo was easily tier 1 materiel in Season 2, and he's fine in S3 (I've recently got back into him as I realised how much fun I have invading constantly). Much the same with Skarner, although I never played him.

Most unconventional jungler I think I've played is Taric, who's not terribly unconventional by most standards. I just prefer to stick to the tried and true most times. =P
