Hi...for various reasons, I need to bite the bullet and buy CS3. I know that CS4 is now current, and if I were a hardcore user, CS4 may be the right way for me to go. But I'm not proficient enough to need CS4 - CS3 will do just fine. Specifically, I'm going to get CS3 design premium for mac. My question is...is it "safe" to buy CS3 from places like saveintheusa.com, estockware.com, or softwaresurplus.com? They're all selling it between $800 and $900. I ask whether it's safe b/c when I go to amazon, the cheapest I see is $1799. Am I missing something? None of the other sites' versions were upgrade versions. I'm just nervous I'm overlooking something, or going to get hack software that doesn't work, or blows up my mac, or something crazy.
