I have some Vectrex cartridges with overlay and instructions for sale;

-SCRAMBLE (cartridge,overlay and instructions - very good condition)
-SOLAR QUEST (in box with cart, overlay and instructions - the box has the top flap missing but in very good condition)
-BERZERK (cartridge,overlay and instructions - very good condition)
-CLEAN SWEEP (cartridge,overlay and instructions - very good condition but the overlay is slightly bent in one corner)
-COSMIC CHASM (cartridge,overlay and instructions - very good condition)

Verctrex games are becoming rarer all the time so jump in. I can give references from other people I have dealt with over the net.
I am a bit hesitant to sell these Vec games but email me and we can discuss the prices. I live in Australia so the buyer would have to pay for the shipping but it shouldn't be too much. I consider myself to be a genuine and honest trader.
