Any of the pre-orders of Family Man volume 1
Gunnerkrigg Court Symbol, Ladies Large
Endorphin Choker Necklace (Prohibitively expensive, but awesome)
Molecule Earrings. I think I'd like Serotonin and Dopamine
Custom bracelet of Oxytocin (amino acid sequence CYIQNCPLG)
With all three, I'd have a complete set of love and happiness molecule jewelry! And it would only cost like a thousand bucks >_>
Starting my wishlist for this year. To be updated as I have more time.
