It will spike the cost on ebay because ebay buyers are stupid.  They will look at what the calculator is telling them today, and dream about the possibilities with stars in their eyes. They'll see that paypal credit ad (6 months no payments!) looking them right in the face and figure it's a sure thing. 

Of course it's going up to $20k on ebay.  No, not because it's worth it.  If people were paying what they were 'worth' now, no one would be shelling out $6500 for one.
