I've been using Poser since version 2.0 and 4.0 was a big improvement over 2 and 3 with the morphing capabilities and ability to use DAZ's Michael and Victoria characters. I never tried the high poly count figures in 3.0 so I don't know if they work properly. Also the transmap capabilities. I agree with whoever posted the message about why there's no low res Michael version. There is too much emphasis on Victoria especially with clothes. I have both 1 & 2 of Mike/Vicky and Stephanie, but I'd prefer to have a low res version of Michael when having to put a lot of people in one scene. The P4 version of Michael isn't bad, but still eats up a lot of disk space and memory and doesn't have a Michael body. I'd skip Poser 4 and go with 5 unless you're looking for some discounts in upgrading. In the long run, you'll be satisfied you went with 5 because it is offering so much more.
