Benchmade Delta Raider???

[Squid]

I've already posted this on the Benchmade Forums, but since the traffic is so much higher here, I thought I'd post it here, too..

Can someone please tell me more about the discontinued Delta Raider fixed blade???

What kind of steel? The handle looks like rubber - is it kraton? What is the tang construction? Can one conceivably replace the handle, say, with micarta? Being discontinued, how rare are they (i.e. what is a fair market price for one in good condition)?

Thanks in advance!
