A few of my favorite RPG supplements come from Dreamscarred Press. I love:
Worldthought Medic - Yes, I know the link brings you to Complete Society Mind, but the linked product contains not only the Worldthought Medic but also WTM-esque several PrCs that are cool, too. What is a Worldthought Medic? It is the cleric you've always wanted to play but were never allowed because you had to be a heal-bot. This class lets you heal your allies according to the damage that you deal with certain class abilities. Beyond cool. Far and away my favorite 3rd party class ever. And yes, youcan buy just the WTM
here, but for the extra $2 just get the compendium. Trust me. If you have ever used psionics, you want this one.
Halo Knight - A great class that while based on psionic power points isn't really a manifesting class all that much. The power points fuel aura-like effects that are beneficial to the character and often his allies. Much like a marshal for psionics fans.
Sequestral Feats - This is a product that is to psionics what Reserve Feats is to Vancian Magic. And it's pretty cool. Not in a Worldthought Medic "blow your mind" cool, but still cool nonetheless.
And, I won't push my own products except to say that you can see them in my sig below.
