i just started to shoot RAW and am interested in learning advanced photoshop techniques. i have an education version of 7.0 and can possibly get an upgrade for $160 or so. i'm wondering if i should just bite the bullet and buy the non-education version of CS2 so i don't have to try to continuously purchase education upgrades as i won't have access to those anymore in the near future. i am interested in buying some books, but they are mostly geared for CS2. are there any good 7.0 books that you recommend and can i "get by" with 7.0 a little longer? i really don't want to spend the $$ on CS2 now... thanks!
