Best/cheapest place to get?
First thing to come up on google was a subscription for $9.99/month. This seems a good value.
Also, I've never really used it before, how to practice?

Anyone?

CS2 for free off of their website.

Thank you.

just youtube a bunch of tutorials, or find somewhere you can take a photoshop class.
youtube will probably be just as good if not better though.

i learned on cs4, got cs2 free, and bought pse...11?

honestly, $10/mo is a good value for the most current version, especially if you plan to use it often.
if it doesn't fit well for you, cancle sub. only $10 spent. no harm done there.

Good point and insight. Thank you

I know its not what your asking but what about GIMP? Do you use the elements that are photoshop only?
