Funny coincidence, I've been soldering together mine just tonight.
I've used Tyco Axicom D2n relays, part# V23105-A5401-A201, which I
got from Farnell. Farnell# is 4219582. This is a 5V relay, but other
voltages are available too. Datasheet is here: http://www.farnell.com/

With kind regards,

I finally finished mine today, and it didn't work. This is because
the relays I recommended above need quite a bit of current (80 mA
each), so the transistor wasn't getting enough base drive to fully
turn on. I've lowered the base resistor from 47 k to 15 k and now it
works fine. This is with a BC337-40 transistor with a hFE of 250-600,
so if you use a transistor with lower hFE, you might need to lower
that resistor even more.

With kind regards,
