Hey all!

I have a Canon 400D with a Sigma 8mm fisheye lens, and I've been monkeying around with PTGui. I'm thinking about getting a nodal ninja, and would like some recommendations for which model would be right for me. I'm a panorama novice, and I'm just looking to learn as much as I can. I hope to at least publish my panoramas on the tubes. Any advice would be greatly appreciated!

Oh, one more thing. I'm mostly interested in doing spherical panos.
