Depends on supply. I got mine from my contact for $90 shipped priority from Japan brand new. That was about 4 months or so ago. But if they are more rare now it could be more. Depends on the availability.
Easily over $75 dollars. Depends on the supply that's available, and with it being out of print, I'm sure it's short. Plus you have to ship from Japan. Not cheap, but you can get it if you really really want it. It is however, much better than the R1 release. PM me if you want and I can tell you...
The Jurassic Park superbit is much better than the R1 release. You can still get them if you really want one. I have a source in Tokoyo who can get you a sealed one but it will cost plenty. He got me one.
