Louise, whether or not the software is worth the price will be greatly varied by persons here, and will depend a lot on what you need and what skills you have.
I have the Stone Cut software and for me personally, it was definitely worth the price and there is no other software package I would prefer. That being said, I think DAS has gone above and beyond to make producing rhinestone transfSers a simple point and click process, with everything ready to go out of the box.
Some will say if you have Corel Draw experience, that you can do all these things with a simple add on macro for Corel Draw. That may be so, but I have no Corel experience, nor do I want to have Corel experience, thus the Stone Cut Pro software and all the things that can be added on via DAS, was the perfect package for me.
Some things I like best are the one click collision corrections (removes all stones that are too close with one click), the sequin mode, the bitmap conversion to rhinestone (also available in WinSignPC).
Again, you will need to decide what level of rhinestone software best fits your needs and outside knowledge level and go from there. There are several lower cost rhinestone softwares, as well as Corel macros, that will get the job done, to a certain degree.
