Well a big factor in the price is size too.
My graphire is 4" x 5". It looks like you can get a refurb 4"x5" graphire for $60 on Amazon  and you can get one new for $100 from Wacom direct .
It may be a combination of the sizes you're looking at (it looks like the 4"x5" version is a bit more rare these days) and importation issues.
