I think you can do better. Dealers will be able to bring down the MSRP on a lease which will lower the payment.
Keep in mind the offers on Kia's site include cash due at signing (at least $3499). With leases, you should always avoid putting money down. If you're in an accident and the car is totaled, you lose that cash.
There isn't a lot of lease price discussion here, but try leasehackr.com's forums to see what kind of numbers have been found.
