I was wondering how Sprint is in Missouri. I'm just looking for other options then ATT some day. The Sprint tower in my town is going to get a data upgrade.
Location is key in Missouri. When I lived in Ozark (few months ago) it was hit or miss due to overcrowding on the towers in that area. I also had issues in Springfield. I was down there a few weeks ago and was still having issues with call clarity and data speeds. I know they are working on it so hopefully those problems will subside. Coverage outside Springfield, Columbia, St. Louis, and Kansas City can be shaky at times depending on the location. Towns are usually covered but I have found the space in between are usually so so. Sprint needs to make a push to cover more of the major roads and improve signal on those roads. They still have a few dead spots along 54 on the 4-lane section and on 36 and 50 just outside KC.

I'm not sure which market area you are located in. For instance, I'm in Portland, OR. but they are not launching just this metro area but working on the entire State plus part of a neighboring one.
If you stay on the interstate and don't travel off of that you would be fine. Sprint phones roam going west toward Fredericktown. If you travel west beyond that the phone toward the Pilot Knob area even roaming is spotty. Native signal is present and fairly strong around Farmington. Going east toward Chester you will roam. There are some areas on I55 where signal gets a bit weak and choppy. There are also dead areas on US67 toward Festus. I have traveled that area a fair amount and I can say it can be frustrating with a Sprint phone once you leave the interstate. Just check the coverage maps and make sure you are in good coverage. If you go with it and you get home to find it doesn't work so well. Take it back so you aren't stuck with a phone and service that will frustrate you over the course of a contract.
If you want someone to say go ahead and get it that won't be me. Due to the limited coverage area and how shaky coverage can be in that part of MO I personally would try to find another carrier.
