I've got these two models for sale.
Both of them come with 50-60Hz switch and RGB cable.

MD1 goes for 50USD and MD2 goes for 45USD.

MD2 still has the instructions!
Both consoles come with two pads and power supply. I think I can throw in a game or two along with RF lead if you want.

PM me for pictures if you're interested.
Shipping within Portugal is free (Don't know if there are any PT users around here). For other locations, I need to check, but I will try to keep the postage price low)
