I unfortunately had to get rid of my Q50 so I have a JB4 for sale. I have the box and all the wires it came with, if your on the fence about buying a JB4 it really woke my Q50 up and was the simplest way to unlock some horses. Let me know if you local to me we can figure out a way to meet up and I am willing to ship to you if you want. Thank!
Edit - I put the price back to $300 I'll eat the inflation :)
