P3DO Explorer Pro 2.8 is back on a 50% discount at Renderosity, for a limited time.
I’d still suggest PzDB as your first choice for indexing and searching across a large Poser/DAZ/Vue content collection, if you can afford it. But it can’t hurt to have a backup option, just in case PzDB ever stops working. For instance, I understand that PzDB 1.3 still has to ping a remote licence-server occasionally, on start-up. Which is less than it used to in version 1.2, where the ping was required at every start-up — but which is still not ideal in terms of having perpetual ‘will last forever’ software.
The 50% off seems to be part of a store-wide giant sale. A quick peep at my DAZ Store wishlist suggests a similar 50% all-site summer sale at DAZ. The latter includes Poser utilities such as aniBlock Importer for Poser and Send In The Clones (scatter and clone scripts, needs AVFix to work, but still may not work), and useful third-party software such as Michael3XprssnMagic (M3 doesn’t have many native expression packs, but can still be useful for comics makers). At the DAZ end of things, LAHM is 50% off.
