I purchased Infinite Dungeons and I can tell you that it really isn't that good. It has a problem with being a little TOO random in my opinion. Levels have no rhyme or reason with monsters, loot, traps, etc.
If you want a better random dungeon experience, I would recommend downloading a script and designing your own setting.
I actually used this awesome script several years ago in my own module and had a blast (trying to find the one I used from NWVault). I was able to replicate a little starting town like Tristram from Diablo with a big 20 level dungeon with random monsters, traps and loot. It was pretty epic. Unfortunately, I lost the files for this mod when my old hard drive died.
Edit: Couldn't find the old script I used, but I found this one
and it looks like a really awesome one. Just import into your own module and play with the settings.
