It's worth the sale price without a doubt as long as you have large processor and lots of memory. Don't try to run this on win 98 or ME. Over a Gig processor and a G memory should do it. I agree with everything Little Dragon said except that I have had less problems with Poser 5 than with Pro Pack-- less freezes for instance. There are some things to stay away from -- cancelling a render to a larger window, for instance. I hear there's a workaround but I don't want to chance it. It is slow,especially with V3 loaded and dynamic hair. V2 and Mike aren't anywhere near as slow. The hair room is a bloody mystery to me, very twitchy-- I use premade dynamic hair and it renders fine. I wouldnt give up the library management and the FireFly engine now. Like I said, well worth the price it is now, if your machine is powerful enough. Emily
