I am still using a Droid X. Mine has worked great the entire time i have had it. Infact, it't the best phone I have ever had. ....... I am up for renewal now and am probably going to get the Galaxy Nexus. But I haven't had many urges to go get a different phone for any reason, because I haven't felt like much was that much better. I am in a 4G area now, so that is something I want my phone to be able to do.
Go with the Droid X. Just find a used one at a good price. No need for a contract with this one.
Good Luck. and welcome to the Droid world.
