The Radio Shack receiver listed on that page works good too for those
too lazy to order one. You'll pay a premium at the Shack though. My
local electronics parts shop suggested I get that one because he doesn't
carry IR Receiver modules but gets requests all the time, so knew
exactly what I was after.
I recommend using the capacitor in the circuit as well (it's in the
diagram.)
