Not that rare, I believe they found a load of new ones a few years back, you can pick them up for Y4000 yen or so. Trying to find the hand full of games that support it is more of a challenge, but Highway Star, Falsion and Cosmic Epislon are recommended (and not on the Famicom Disc System).
They regularely pop up on ebay, so not that rare I guess. Although there is a special one for the Twin Famicom if I am not mistaken which is very rare.
Yup that is correct, though not too rare, the Famicom 3d system is absolutely superb and gives a great 3d efffect due to it's use of not just glasses but a shutter system too, and the 3d games that support it, especial hot rally by nintendo are excellent for their time. The sharp licensed model is extremely, and I mean extremely rare, and don't expect to pick up the twin model for less than a thousand dollars.
I am going to have to search eBay for one of those cause I have never seen one and it looks pretty cool...
