I have a A'Pexi FC Power standalone ECU for any Subaru that has a version 5 - version 6 WRX/STI ej207 motor and harness in it.
Specifically for those motors and ECU, so don't ask if it will work on your other models!
I used it for a bit and it worked perfectly fine, but decided to go with a Link G4+ instead.
Has a minor tune on it. Nothing major. Just bolt ons.
Great since we can't tune JDM v5-v6 ecus here, so this fixes that issue.
Asking $550 shipped and Paypal'd for the ECU with the FC commander for it.

Feel free to ask me about anything I may have missed.
Thanks for looking!
