I'd say get the screens filter. The other ones like lens doc and perspective are really things I'd rather not have automated personally... because you won it, get something that'll be fun. Lensdoc might save a few moments, but it looks kinda boring... The screens filter looks like it can do a decent job of replicating the real world in terms of screen printing and such. If you were to actually do screen printing, it would be HELLA f'in expensive... case in point, remember when I won Aurora? I STILL aven't used it once, for all the bitching i did to Digi-element to get me a working serial and activation code... but im doin photo again soon and i know its gonna be kickass fun. May not be the most rtechnically useful, but its gonna be a blast.
