Quote - I'd rather see a plain ordinary "bad" render than something so doctored up that I don't know what I'm getting.  Personally I think post working images in the MP should be forbidden.
I remember one package that I was interested in. I spent a good 30 minutes looking at the promos and what was in the package, only to discover that a good 80% of what I was seeing in said promos was post worked in, or parts of other packages that they either sold or from other vendors.

I learned the hard way to scrutinize ad pages because what you see is not always what you get.

Give me plain ordinary, bare bones renders any day so that I can actually see the package, not something so doctored up that I'll never be able to achieve.

but no one said anything about doctoring.  bad renders are just that.  i've seen products that i knew could be used well in Poser because the merchant posted development renders from another application they were comfortable with, while their Poser promo renders looked like bad P4 renders.  conversely, i've seen products i knew were low quality just by what they didn't include become incredibly popular because their promo renders looked great.  not postworked, just good clean renders.

personally, i have a default white room scene that works very well for me before i even start on postwork.
