DAZ lets you re-download your purchases whenever you want, so you can always get new copies of your V3/M3.

I confess, I use the store databases rather than keeping my own, and it's often easier to find the product and re-download it than find it my own archives.  (I don't think I've even downloaded everything I've bought.)

I guess I'll regret this if the site goes belly-up.  Like PoserPros...
