I'm another that started with Poser and then tried out Carrara and found it seems to suit me better. Being able to do almost everything in one program without having to learn different interfaces and workflows is great for the lazy hobbiest like myself.

Still at an early stage of learning with it though, just wish there was a Carrara version of BB to get shader advice from! Driving myself nuts at the moment trying to work out decent shaders for eyes to get realistic reflections in the right parts of the eye.
