Frankly I still think 44 cents per completely unique icon is an incredible price. These "hue shifted copies" are also not quite so easy as you might think. It still requires manual selection of colours based on my existing palette which isn't always completely straightforward, and also relies on the colour theory skills I've spent many years improving. You won't find a library of 32x32 icons of this quality or consistency anywhere else at the moment.
Ultimately, it's your call if that doesn't suit your budget, but I have spent years building this icon library and put countless hours into both paid and free packs. Suggesting I cut the price to 10% of my original asking price is pretty insulting, and I'm not interested in charging such a small price for my hard work. Thanks for your input though. :)
