I got lucky, and picked this one up for $400. It does have some cosmetic issues, and could use a real good waxing... and has a couple of lights that stay on...lol But the Matrix works perfect and alll the sound and voices work... and someone took real good care to label the wire, and where they go, and take pictures. All the rubbers were replaced already.
I got a packet with all the instructions, a quick trouble shooting guide, common issues, pictures of all the boards labeld like the wires... whomever had this was as OCD as me!...lol
