cajomi, If the product is of the quality of the website it should be worth the price. I would suggest a time or usage limited demo so that people can play with it a little before buying. I'm a bit relieved that someone else has taken on the idea of PGM import even if it isn't going to be a free program. It sounded as though you're using the 32 bit Geotiff format. That was a fun idea for me to learn and I thought it would good to see it implimented in an advanced application. all the best, -TJ (author of "Tiffer")
