LaserSoft Imaging

i just tried the AI studio demo for my nikon super cool scan 4000ed. worked great. I now would like to determine the price for this software which would enable me to use the slide scanner mentioned above and my EPSON perfection 2400 flatbed scanner. i cannot seem to figure out the price on your web site. i want to be able to use both scanners at different times.
thanks

Dear Customer,

as we optimise SilverFast for each Scanner individually you would need to purchase 2 Versions of SilverFast.
You can check the price with our PriceCalculator http://www.silverfast.com/product/en.html
