No one thinks that you're cheap.
If anything... the lab products are cheap... in price that is, not quality.
As far as the watermark... I'm pretty sure that you know the reason for it being there... we all know why it's there, so let's respect the fact that it's there.
I know... I know, that this software is very exiting when you first witness what it is capable of because it's very well... damned exiting. I didn't even try the demo, I bought Visionlab as soon as I realized that... this is what I need for what I want to accomplish.
I would suggest that you not worry about the watermark... keep practicing with the demo, that's why it's there... purchase the license when you can get the funds or wait a little while because FXhome frequently runs specials. You know what that means right? It means that the price will be even lower than it already is.
