Motorola MPx220

I want to buy any one of these two phones, where is the lowest possible price for these phones? I think SMT5600 is better, but if I can't find it from a good retailer, I'll go for MPx220. I want to get the phone to be delivered on Monday!
Thanks

PS:
Do check resellerratings.com before purchasing online, intelenetwireless, a1wireless, wirefly, inphonic are all very shady.
