Hi all -
I use Paradigm Concept's Psionics Unbound for our house game. It's the Expanded Psionics Handbook with all the errata already done up (like the Astral Construct is fixed). Plus a few new psionic powers. I however, don't really care for the classes, bcause they are overt for their Arcanis campaign setting. So if you're using the base classes from the XPH, then the PU for the powers and such. Because I have the PDF of the book, I printed it at my college (for real cheap), and added in HyperConcious as well as the Complete Psionics powers and feats. Plus I'm playing an Erudite from CPsi so it helps to have all three books of powers and such all in one place.
I've also looked at the Dreamscarred Press stuff and have been very impressed, but not enough to use it in place of Psionics Unbound/HyperConcsious.
Be Well. Be Well Combined.
