Good place to buy a JDM D16 motor??

I'm looking for a good site to get a good deal on a D-Series motor. The only site I've found is http://www.hmotorsonline.com/shop/sc2000search.cgi?what=page&item=30019 they've got it for $585+ shipping (including the tranny). But it's a D15b and it doesn't come with an ECU. I have a '94 CX so I'd kind of like a different ECU than I already have instead of getting it programmed. Any help is greatly greatly appreciated.
