I have a nice opportunity to purchase low priced student Adobe Suites right now as i am enrolled in Photoshop CS4 and Illustrator CS4 classes. Here is my concern: I would like to purchase the Masters Collection or the Design Premium. Both of these suites have Photoshop Extended. They do not have just plain old Photoshop. Will I be confused or unable to use PS Extended if I am learning standard PS in my class? Will the DVD of lessons for my class (including images that are to be manipulated in standard Photoshop) work with PS Extended?
