It might sound naive to some, but you get what you pay for. It's as easy as that. Photoshop is miles away from Paint Shop Pro, but if you are short of cash, you won't go wrong with PSP7 as it has all the needed tools for a great variety of graphic design jobs. But I have to admit that after buying Photoshop the money invested came back much more quickly than I thought.
Those who don't pay for software plese don't say anything, I always prefer not to eat for a week and buy some software, The constant upgrades and support are very very welcome to me.
