--This unit will read RFID tags and communicate the data to a website via a GSM module.--It will simultaneously communicate via Xbee with another Arduino with an LCD screen.
Just my opinion, but go with the Mega!A "genuine" or the VERY excellent SeeedStudio Mega Clone!The SeeedStudio Mega is cheaper, has a JST connector, which makes for a better connection in a fixed project.And it's sexy red!
