$17 shipped, includes 4551 chips pre-soldered. These chips are for region modding TG16/PCE/Duo's. I had to change the pinout at the bottom so it would incorporate both SMD and DIP MC14551 versions. The H-A were not supposed to be there so on install they should be ignored and it goes like this

Also when installing instead of using a 5V source, I have found that using the IN pin on the Voltage regulator is FAR more stable and you won't have issues where some games will crash after a few minutes of play.
