Hey! I know this post was from quite a number of months ago, but if you're still looking, there seems to be a classic Somari famicart going on eBay right now (albeit not for a great price). Still, if you're interested, item num. is #144610043710 (I'm not the seller, and there's no guarantee it'll work or whether it's a legit seller - always be cautious when purchasing items online. But, happy hunting! ★).
