As a general rule, the breadboard + power supply kits don't save you
that much and are a lot less flexible than separates. In addition, you
may want something other than +5 if you ever use op amps or lower
voltage stuff. Something like this

a while. It's not Lambda Power but still...
It would help, though, if you could mention some specifics about what
equipment you have in mind.
