If you can't afford that, I recommend getting PhotoShop Elements, which is what I use. It has 99 percent of what PhotoShop has for under 100 dollars. Since my dad is a prof at the local college I got the educational version for 70 dollars.
What she really needs to invest in is a good graphics tablet. I use the Wacom intuos2.
On my site, all digital images were created using Photoshop Elements v1.0
