Not sure if this is a bargain or not. When I bought my Plustek 7500i it came with SilverFast SE 6, which I used until it stopped working with a Mac OS upgrade a few years ago. When they introduced SilverFast 8 I did try a trial but didn't fancy the price for the upgrade, and moved to Vuescan Pro. That's been pretty much OK for me, although frustrating at times and sometimes a bit limiting.
Now out of the blue LaserSoft Imaging have sent me an upgrade offer from my defunct SilverFast SE 6 to the top of the line SilverFast Archive Suite 8.8 for only (!) €119, valid until 25 September. I don't think I'll bite, but if any others used to have SE 6 it might be worth investigating....
