Quote - I've yet to have a need to try to sell somebody else's product. So no suprise there.
 I doubt any other user of a conversiont tool is thinking of trying such either.

Who is selling someone else's product? And if a conversion tool isn't producing commercially viable conversions then it isn't doing a good enough job. By commercially viable, I mean converting it well enough that it is comparable to the original product. No wrinkling, no loose fitting, etc.
If you purchased a refit piece of clothing and it contained these thing, you would complain and get a refund.

Quote - I've seen a lot of good work come out conversions.

And that's terrific for the general user. For the more experienced who wants top notch results, conversion tools aren't necessarily the best answer.

I'd guess I've been using Poser longer than you even knew it existed, so I do know what I'm doing. I have used every conversion product available, and tweaked after it's done it's thing. For me personally, I still don't see commercially viable results. I believe if you're going to do something, do it right. What's the point of converting something if it's not going to be as good as the original? Perhaps I just expect too much.
