Understood, but tread warily. 

Poser4 when I bought it came with a lot of models.  These were complete - one did not need you to buy extra texture packs, clothes, pose packs and so on - I just found them very ugly and do not know how good the current stuff is. 

DAZ marketing policy is very astute - and yes, their stuff is good, but you could find yourself running through that $200 quite quickly and then wish you had spent it on Poser7 instead!  

Examples of a recent annoyance:

1. The free package from DAZ includes a cat, with some poses.  No textures, but sure, you can search and find them on the internet I think.  What was annoying that the cat as supplied could not open its mouth.  $34  please to get that (with textures and so on).  Instead I use the cat (and the dog) from Poser4 (they are actually Poser3 models).  At least it could open its mouth.
2. I bought the V4.2 Pro pack.  I contains a Morph to create Helena, who is a bit more endowed.  I cannot get the clothes supplied (i.e. undies, a lacey blouse, a coat, some shorts - that sort of thing), other than the pants with a bit of fiddling, to fit Helena as she is a Full Body Morph.

It may appear that I am unhappy with DAZ, but actually I am delighted with my purchase at a special price of $25 'instead of $99' and the free DAZ Studio and its contents.  When it comes to buying more stuff I recommend though that you check thoroughly what the package contains beforehand, and to be honest if I had the spare cash I would be investigating Poser7 very closely myself before treading further.....
