those other progs have some tremendous learning curves but once you really get the hang of them, they're amazing. try the demos and then decide. at first you'll be frustrated but that's normal. i use lightwave from newtek, and there's a plugin made by greenbriar studios that should help you import poser figures. i guess the pro pack has a plugin too, but i've heard mixed reviews on that. either way, good luck. most bigger apps will give you different abilities that you can't find in poser, such as volumetric clouds, particle effects, realistic hair and fur and grass, and, of course, modeling :)
