You might take a look at the ULN2003A. Inexpensive and available. It
contains seven transistors, each able to carry up to 500mA (from memory).
On the relays, make *sure* to use the diode across the coil to capture the
collapsing field. I believe the ULN2003A datasheet is on our web site in
the EDE1200 section. http://www.netins.net/showcase/elab
