Halted Specialties in Sunnyvale always has lots of wall transformers
at reasonable prices.  They have a test bench at the store where you 
can characterize them before buying.  They also sell 1000 foot spools
of hook up wire.  While you're in the neighborhood, you can also
go to Fry's electronics, up Lawrence expressway about a mile.
