I like '1284Ps. I have used them in several variations of boards, pictured here. Bare PCBs available as well for DIP and surface mount parts.

Boards will accept any of the 40 pin DIPs/44 Pin TQFPs: 324x, 644x, 1284x.
Setup the IDE
Select Bobuino as board type for mine.
This one for instance can be used with offboard FTDI Basic/FTDI cable, or CP2102 module, or install a MIKROE483 on board if want 'built-in' USB support.
