Source for Eichler Interior Doors?

I need to replace my interior doors. Last time I replaced one, over ten years ago, the big box stores carried plain Lauan door slabs but that no longer seems to be the case. All they have are white primed raised panel monstrosities. The home depot people told me the plain door slabs were no longer available even as a special order.

Does anyone have a recommendation for a local source for Eichler compatible interior door slabs? Please send a PM directly. 

Thanks,

Andrew
