As a research scientist for the UW, I think I can field this one. Try Sigma Chemicals: http://www.sigmaaldrich.com/Area_of_Interest/The_Americas/United_States.html They are huge international corporation with very reasonable prices and have more chemicals than god. I'm pretty sure that they will ship to an individual as well. If not, contact me offline and I can probably work something out for you. -----Scott R.
