I use Paint Shop Pro 7 for all designs and slicing. Tried Version 8 and didn't like it at all. First time I've been disappointed with a Jasc product.
I started with PSP in the beginning because it was so much cheaper than Photo Shop. I still use it now because it does everything I need it to and takes all Adobe plugins. Glad to see there's a few other PSP supports.
Everything in my portfolio was done with PSP.
