Here's my 2 cents worth, if I like it I will pay for it. I'm on a fixed income and this is part of my entertainment. The work that Tom, Andy & Kitty (and the other Master skinners) do is worth every penny I pay. I can't afford to buy too many every month, so I pick out the ones I want right now. Yes, you have to pay for the software, but what good is it to have skins if you don't have software to use it on? It takes time to create the skins they make. Just my honest opinion. I'll get off my soapbox now.
P.S. You guys make my day.
On another note, is the new version of WindowBlinds capable of running XP & Vista skins?
