If you want the best price, I would try someone like Big Boys Toys or one of the others that list them. You will be limited on options from them, such as finish or milling, and the deliver might not be to good either.
If you need any special service, like getting one unmilled and un-anoed (is that a word?, well, I made it one!), or even the milling they offer, you may want to go direct to AKA.
They will offer great service, and more than anyone else would. I got an un-anoed from them to mill on and, now I am going to have to get it back to them once it is finished so they can assembly it and ship it back to me.
Who else would offer that?
