This is exactly why they are hard to come by and expensive when found.
When these cards were new, only a few were made and were sold to the folks willing to spend money at the time. As the years passed, everyone can to realize how good these cards were... and said " ****, why didn't I buy it back when"
Now it's a limit of... there's only a few and everyone wants one.
I have one too, It's in my 4000 and why should I give it up, unless it's for a lot of money because, IF I sold it, I COULD NOT replace it!!!
