I hink I spent $20 once for an outfit for V3 but I had a special need and it was perfect.  I collect freestuff even if I need to retexture it or even map it.  I have the time but not the money. 

Poser stuff has always been underpriced compared to other applications but there are good reasons for that. For me $15-18 is fair for a nice item is not a problem.  The more flexible the item is the better.
