I also agree that price and then quality of sounds plays a big factor for me. I am not a big orchestral composer like most of you, and I go for the libraries such as Plugin Guru, The Unfinished, and Orange Tree Samples to name just a few. These are sellers I know and that have great affordable sounds/effects I like and use and don't have to mortgage my house to pay for them. Protection is not a factor for me, if it has it that is great. I am not too fond of using ILOK products, but if I would need it in the future I would get it.
Most sellers have good demos and walkthroughs, but i also watch more videos or get opinions from others that have the product on if that library/effect would fit my needs. Plus i keep watching the VI forum and learn from all of you about products.
I will sit back and see what 2018 brings me far as affordable new sounds.
