I've got three Acopian A5MT510 supplies feeding Node 130s through PD Creative boards. All sound good to me. The power supplies show up on ebay, and surplus dealers sell them, usually under $100-. The "A" series have better specs than the "B".
Not sure why Pavel didn't respond; he is usually very prompt. Your emails might not be getting to him. BTW, the boards are on sale right now for 260- zloty, about $63-. The first shipping quote I see is the highest of the three choices offered; if you proceed shipping usually costs about $20- and takes a week. I see the LHY at $119-, don't know about shipping.
I have no connection to PD, just a happy customer.
