Where can I get residual and money factor info for 2010 Prius

Any one know where I can get an up to date information on money factors, residuals etc... to calculate a lease for a 2010 Prius II or III model?

I negotiated a price of 21k on a demo III with 800 miles on the odometer. I'd pay all dealer and registration fees out of pocket. No money down on the actual lease to reduce payment. Sales tax rate of 7%. Any incentives I should know about?

If I can't get a good lease price on a "new" prius I'll finance a used certified one.

 

Forgot to mention msrp was 23900.
