and click on the thumbnail for the comparison photo. Shows sample 
comparing several resizing programs. It appears SmartScale is 
superior, but not by a whole lot (therefore price will be an 
important factor), to Genuine Fractals. The biggest benefit, in my 
opinion, is how smoothly SmartScale interfaces with Photoshop -- much 
better than Genuine Fractals in this respect, and with equal if not 
better results.
