I found a 5 pack of these on eBay for $10. They're shipped on a slow boat from China. I'll let peeps know if they work or not.
Some I've found are rated at 2A, some at 3A, and a HPCE (high power connector) rated at 9A. I'm guessing the power rating is not too important? Since this is a 16bit data bus expansion all/most of the power is being pulled through the 8bit side of the connector - that's my hope+guess. Anyone have a source that can thumbs up/down that opinion?
