i'd vote for the AGA-T2. glass tank included so no issues that way, and its quite easy to grasp and doesn't hurt the wallet. i picked up one of those only to find that i prefer rebuildable drippers.
I know it doesn't fit your request, but maybe an igo-L cheap dripper would be a good way to delve into rebuilding. i feel like silica/ekowool drippers are more user friendly than trying to jump right into genesis types with steel mesh wicks to worry about shorting.
