It's sure as heck worth $99 and even $150. I paid full price-- $359 and I owud advise no one to do that. However, with a big processor, Win XP and a ton of memory, real and virtual you should have little problems with basic Poser 5, material room and FireFly. It is slow. If you have NO Patience, forget it. You cannot do what was so cool with Poser 4-- run a quick render to make sure everyting is okay. That was hard to let go of. But Firefly is great, even my non-poser friends who get subjected to my renders noticed the difference immediately. And now that I'm just beginning to get deeper into the material room, there's so much potential there. Note, I have not had problems with lighting freezing poser up, but others have. I use all kinds of lights but not the ones from Poserstyle as they had a known prob with P5. And you cannot cancel a render -- especially into a larger window. Sometimes you can in the display but I just eliminating canceling renders period. The only other problem I occassionally have is when Ihave loaded something new--sometimes Poser can't find the textures and freezes on loading them. I cancel out and reboot and it works fine. This has not happened in the last month, even though I've loaded a lot of stuff, so it may be getting used to the extra four runtimes I have linked. Keeping the Poser 5 Runtime as lean as possible-- I have only V3 and her morphs in it-- has improved my speed in working about 100%. It's also important to work with V3 in a lean condition-- that is use the Injection Pose Builder from Daz to eliminate all the extra morphs before you work with her. Emily
