^^^ Echo this. Bought the same thing, got a $8 Star Trek to tear open, had to do a little plastic snipping to get the posts to match, but whatevs. Works like a dream now and my Vectrex lacks only an arcade control panel to be "complete muhahahaha"
Richard is not sold out. He is currently selling them minus the cart case. Email him directly if you want to order. His looks to be the best multicart for the vectrex. I have the sean kelly one and I am going to be replacing it with the vecmulti cart.
