I came across this link today.  You can get the SMT 5600 for $224.99, with $225 of mail-in rebates if you sign up for a new account with Cingular.  Otherwise, you can save the extra $204.96 if you were planning on buying it from Expansys, who lists it for 429.95.

If I hadn’t of picked up a JAM, I would be all over this.  Halfway thinking of picking it up just to have a dev smartphone..

Cheers!
