Most people buy it... but since it's kinda expensive only the diehard professionals buy it....

The latest version of Photoshop is Photoshop CS and is around $590 US. You can get the older Photoshop 7.0 for $130 US.

There are of course cheap alternatives. Adobe makes another version of Photoshop called Photoshop Elements which sells for $90 US. It's basically a stripped down version of Photoshop.

And of course there is Jasc Paintshop Pro 8($85 US) which suits a lot of people just fine.

I recommend you try the free tryout versions of Photoshop Elements and Photoshop CS. Please click the link below and scroll down to near the bottom where you can download a tryout version:

Hope this helps you.

Edit: If you live in the United States or Canada it shouldn't be too hard to find. They sell it in Walmart, Office Max, Office Depot, Best Buy, Circuit City, Sears, Staples, Target... you name it
