I can't discuss that here, but no, I currently am using the demo version available from the website, and I plan on purchasing it shortly. It costs £70 for students, which isn't too expensive, but £600 if you're not...which is kinda pricey.
Hi, thanks for the message. Unfortunately, all of my skills are self taught, so I imagine I'd be the worst teacher you could imagine for Photoshop. I've actually not used Flash properly yet (although I do have it). Most of my published work on this site is made in Cinema 4D, not Photoshop. I'm sure there will be some good tutorials on the internet, but I've never used any before, so I'm of no use (sorry). I guess the main pointer I can give is, have fun! Do stuff you enjoy and you'll enjoy learning Photoshop and Flash.
