CDMA phones are going out of style, man. To my knowledge, there's no company (or very, very few. Maybe Telus in Canada) that carry CDMA phones. Most come with a sim (and newer phones are making micro-sims more popular)
That kind of phone would probably be worth buying if you lived in Europe or maybe Asia where there are a few major cell phone brands that still carry it, but they'll end up switching over to GSM because it's cheaper for them and more effective for a customer.
