Growing away from Support

I been in this game for about two years now, always had a laptop to play with and only used Wi-Fi, so my connection was bad. Playing support was the only role managable with my connection. So got good in support role.

Now with a computer and ethernet connection, this game is 10x better, but playig support is tastless to me now, yet being forced to play the same role, has made me good in it, and with that, finding it difficult to learn a new role

My interest is Jungling, but finding it hard to find the right champion, attempted to use shaco and...well that failed hard. So anyone have tips into a good champion to start with? (Other than yi, since he gets banned/taken a lot)

Basically a champ that can help me transition from support, then from there after some practice I can find my main jungler.
