Personally, I can't tell the difference in the renders. They're showing them side by side at DAZ and I can't see anything different between them. When Vicki's came out, I got the standard res ones. Not only were they almost half the price, but I heard some people complaining that the high res ones didn't render and caused crashes. I would suppose the high res ones would be good for very detailed work, but I think I'll just be getting the standard one. Melanie
