I only have 2 different versions.  What is the plural of nes anyway?  Neses?  NESS?  I don't know how that works.  Maybe NESI?  Anyway, I'm a fan of the toploader.  It works the best time and time again.  Then again the old toaster has worked for the past 20 years.  Well, 21 this Christmas.

Welcome to the forums, enjoy your stay here. I think the toaster is still my old time favourite. Toploaders give that irritating line on the tv with alot games. So the toaster all the way.

I would say that the best system that is affordable is the famicom av.  I use it all the time and it works great and doesn't have the horizontal line issues that the american toploader has and it uses av instead of rf.

I'd love to have a famicom twin so I could play some disk games but the famicom AV is pretty nice and they were all manufactured up until like 5 years ago.  I got mine for $50 plus shipping plus I had to pay an extra $20 for a sturdy 60 to 72 pin convertor.

AV Famicom - It's basically a US toploader with an AV output instead of the RF.

Twin Famicom - Has both the Famicom and Disk system in one unit.
