And to be honest, you might ask some of the merchants from any of the stores around who their testers are and why they use them. Merchants don't always make the best testers (no offense to anyone)some do some don't, just like not all testers are good :) I'm just saying don't assume they are good testers just because they are merchants :) Are you planning also to have the packages compatible with Poser 4 and Poser ProPak? If so, you will also need testers from those versions too :) Good luck with your product!! Pendy
