I have my Zeal Plug and play S4 Megasquirt up for sale. It is a very good unit, just that the tuner I found specializes in Microtech so I am going with that unit instead.
It is in Like new condition, there is less than 30 minutes of run time on it. Here is the For Sale link. Thanks to Muythaiboxer for all the assistance.

$500 shipped
