Back before the turn of the Millenium, I bought Poser 1, upgraded to 2, 3, and 4 and played around from time to time.  Then bought the Pro upgrade to 4.  Started to get into it after that.  Bought a couple of misc content CD's from Zygote, including the Mil Woman.  Then I got a full CD of Poser characters from CacheForce/Planet Poser.  Played with those and various freebies until I encountered BBay, then found Zygote had spawned to DAZ3D, and stumbled over Renderosity from something I read at DAZ.  Off and running ever since.  Used to have a pretty well paying complex of jobs, and for a time I was spending $5k and more a year on content (mostly scenes and sets, to tell the truth, 'Tho I did get all the base Gen 1, 2, 3 & 4 figures from DAZ3D and some base textures and enough duds to use in most contexts).  Economy crapped out, 2 of my businesses closed, and now I have to watch my pennies.   92% of my "aquisitions" now are freebies.
