New clusters are about $1,000, but a company called Beckmann Technologies sells rebuilt units for less than half that amount, IIRC.

There are also a couple of companies on ebay that will rebuild yours for about $200.00, but you have to send them yours, so you won't be able to use your car for about a week.

Here's one for $225.00 plus shipping:

Here's one for $199.00, shipping included:

Both appear to give a lifetime warranty.
