My review is available for free on Dragonsfoot.org, another very well-known OS D&D forum.
@mods: If it's taboo to mention other fora on this one, I'll remove the linky.
I'd say it's okay to mention other forums here. If suddenly everyone goes away and I'm left alone here I probably would resonsider, but it seems like we have a decent following and I don't mind sharing.

A man may do both. For not we but those who come after will make the legends of our time. The green earth, say you? That is a mighty matter of legend, though you tread it under the light of day! —J.R.R. Tolkien
I went through room by room and converted the monsters to 1e. I also balanced the adventure so each level corresponds to the approximate level of the PCs. Basically, the module is set for third level characters to start. So the first level of the palace will accommodate a third level party. Add a level per new level of the dungeon and so on, in general. I went old school with that so basically you can, and should, level your characters as you progress and the monsters get tougher. None of that training crap. Get your dice and go. Characters will not generally advance more than a few levels, but pretty close. The palace is five levels. The layout of the module is set so you can compare the original to the conversion. I had to make some fixes: a bunch of third level characters might have a problem walking in on five hungry vampires...but I tried to stay close as possible to the original.
By the way, if you want one signed by Peter Kerestan (the original author), I have some up over at RPGmarketplce.com.
Finally, Pete wrote a new forward for this module. It is pretty cool to see his notes on producing PotVQ way back when!
