New maxima owner. Need new ecm programed
 

So I've just purchased a 2010 maxima sv and the ecm is no good. Sent it off to be repaired but was told the processor on the board is non repairable. Where can I get a cheap used/refurbished one also what is the cheapest way to get it programmed to work on my car because I don't have the 2100 that the nissan dealership is charging.
