I have The source book for explorers, and it tells the cost and rarity. The ECRB doesn't seem to do this. Am i missing something? If so, can yo give a pg number, if not, how do you buy droids?

p. 409 EoE.

There some droids listed for purchase in EotE. They are in the back if the book with the Adversary profiles. I can't remember the page number.

Purchasable droids across the books: http://swrpg.viluppo.net/equipment/gear/category/18/
