Batteries Where for art thou batteries!?

I recently received the host I bought from RJneal and realized it takes a AA sized battery at first I was gonna use the host for a PHR build but then I thought it would be better to use my 815 since it can run off a single li-ion, however now instead of have my 445 and teh 660 I jsut have teh 445 running, no batteries for the PHR or the 815 plus I need a driver for both.

So I pose the question where aside from DX are good places to get batteries, and I'm not refering to just AA or AAA but also 1/2AA, 18650, 1/2AAA, RCR123A, and what ever other sizes (Size references List of battery sizes - Wikipedia, the free encyclopedia), and they'd need to be rechargable Li-ion poly or Fe or other compound, so far I've found 4 places but they are still somewhat limited on size choices.

Again for cell size references:

The 4 websites I've found that sell a decent array of LI batterys.

3.2 volt Lifepo4 Lithium Phosphate Batteries for outdoor solar lights. Some popular numbers are 14430 and 14505.

I'd Like to find some other places that have a larger array of cells, if anyone knows of some other places please post.
