The two numbers are not comparable. One is the business cost to a
company including all the internal, absorbed costs (see Steve's email),
while the other is the pricelist of the supplier, without internal
user-company costs.
If we compared each method using the other's methodology, passwords
would "list" at $0 per reset, and tokens recoveries would "estimate" at
$105 to $205, plus shipping.

It is a typical claim of the smart card & tokens industry that that the
bulk unit cost of their product is an "important number". This is
possibly because the sellers of such product cannot offer the real
project work because they are too product oriented and/or too small. So
they have to sell on somthing, and push "the number." It is for this
reason that IBM once ruled the world, they bypassed the whole
listprice/commodity issue.
As a humourous aside, here's another deceptive sales approach available
to the token world, the end of "something we know" security, as we know
it :)
