I am currently using LTE connection card with a Cradlepoint router, but am going to have to dump that solution (speeds/bandwith are great, but going to become capped soon). Unfortunately, where I live my only real option is cable (Time Warner). I plan on purchasing my own modem to avoid modem fees, but am not getting one with built in WiFi. I know I could continue to use the Cradlepoint as my router, but was considering looking into either the AirPort Express or a Refurb/Used AirPort Extreme (previous Gen) which should be around the same price. I was wanting to know what are the main differences between the AirPort Extreme (previous Gen) vs. the AirPort Express? I am not opting for the new AirPort Extreme due to price, and that I don't for see me upgrading any of my main Macs (2012 iMac and Wife's 2011 MBA) anytime soon.
