Source for JDM H22

OK, I have been doing some searching and now pricing on JDM H22's. I would like some input on where people are getting their motors from. I would like to get a complete motor, tranny, and ECU for the swap in to the Accord. I have found a number of online places, but am not sure who to trust and who not to. I am looking for input on any of the webistes listed below for sources for the H22 motor and any input on other places to pick everything up from:

http://www.totaljdm.com/
http://www.a1jdmengines.com/
http://www.ardperformance.com/
http://www.importstreetscenes.com/

I think those are the ones I have found so far in my searching. Obviously I want to go with the best motor for the money, but I don't want the cheapest motor just because it is cheap. I want good customer service, I want a reliable motor, and some place that knows what they are doing.

Any suggestions or input? Anyone I should consider staying away from? Any of these places actually start up the motors and make sure they work?

Thanks for any and all input.
