I would like to create a hand drawn animation similar to the ones done by RSA Animate (see on YouTube, can't include direct link, sorry).

Can you folks give me some advice about what software and lights would be best to use? I'm eyeing Adobe Premiere (as I don't have a mac), but can't decide whether Premiere Elements would be enough or if I would need the PRO. I'm new to video (have been trained as a graphic designer) and feel a bit in the dark...

Any help would be appreciated!! Thanks!
