Any scanner that can do trunktracking for an EDACS system will work. For example the Pro 163 or 164 from Radio Shack are good scanners.
If you want to expand a little and listen to the Kennedy Space Center you will need a scanner capable of hearing digital signals such as the Pro 106 or 197. Again both are from Radio Shack.
I'm showing my bias toward RS since that is what I own. However there are a number of scanners made by Uniden which would also be excellent for your listening. I don't know the models, but you can do some research and find out the information.
I'm not sure where you are coming from but welcome to Central Florida.
