Downloaded CS5 Extended trial version.
Great programs in that suite, but mighty expensive to buy. Shaunna and I have Photoshop Elements 4, which is enough for our needs along with PaintShop Pro 12. I don't know that we'd ever use CS5 enough to warrant its cost... a bit under 3 grand in Oz bucks for the complete deal via a retail store, or about $1500 online to downloaded the extended version.
Or if we ever used it enough to warrant the expense, we could go via the upgrade version from Elements for about $865 online. Not that I see that happening anytime soon, though.
