I used poser in a job I did for about 5 years, but we didnt use it as our primary software, it was more like a quick cheat to make the daily deadlines
We were using it to create characters very quickly for a 3d daily cartoon strip, we were posing everything within the software but were then exporting out to Maya as objs to surface and redo the clothing, we were then attaching heads that were built and rigged in Maya, then rendering into Maya built scenes etc to fit the comic.
Over time we began phasing it out as poser has a very distinct look about it and you can tell it a mile off after a while and it becomes almost stale. Also you want control over your characters and by building them in Maya it frees you up to customise them to your specific ideas, other wise you end up with somebody else software and model, its always best to keep things individual in my opinion.
Its great to get you going in 3d but after a while it does get a little boring as you realise it very limited in what it does, you cant build a car in it for instance...but give it a go by all means it may suit your needs...
