Jeezus!  A friend of mine bought one from a dealer for her '90 Accord
about 8 years ago.  Cost was about $60 and she ended up going back and
making them refund some of that when she found out that the list price
was less.  Also, installation is about a ten minute job.

Not sure what vehicle this is for but I can't imagine that the price
has gone up that much.

I thought I needed one for my '94 GSR about five years ago.  When the
car was cold it took about 5 miles before the speedo/odo started
working.  I took it to the dealer and they diagnosed it as a
speedometer problem which was very expensive.  I passed on the repair
and (get ready) the speedo has worked perfectly ever since.  I am
guessing that it was a loose connection.  They may have disconnected
it to test the VSS (which tested fine), then reconnected it securely.

I would sure give that a try before you pay $250.
