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 old and possibly non-working Poser utilities such as aniBlock Importer for Poser (still works?) and Send In The Clones (scatter and clone scripts), but also useful third-party software such as Michael3XprssnMagic (M3 doesn’t have many native expression packs, but he can still be useful for comics makers).
