8 add-ons for RPi, I only like 2

Nice article on different plug-in hardware for the Raspberry Pi, but I only like the last 2, the Razberry for home automation (but a bit pricey at $70), and PiFace Digital for interfacing A/D ($30).  Everything else…well there are cheaper solutions (not including the 1st item, the RPi camera).
