The price is certainly tempting, but unfortunately there is too much junk that hasn't been updated in years. I'd rather buy them individually, even if it means paying more in the end.
That's fair. And you can always try out the free demo first. The next update is just around the corner BTW. I try to do a new chapter release every two months but this time I had a GPU dying on me so I'm like a month behind from where I would normally be.
