OK, I loaded this up for a 30 day trial. To me, this is CLEARLY the best RAW engine out there. I'm mighty impressed. I'm hooked on it. Here's the rub: $500??!! Is that figure correct?? Yeah, I like it a lot, but 500 bucks? 1]Does anyone else here like it? Long-time users, what are it advantages and disadvantages? 2]Any way to obtain this for less than $500?
