For a solderless breadboard. there are some that have bannana jacks. I'm
using this board: mouser# 383-K242
atleast, i'm pretty sure thats the one. it's PSP brand. $22.75. To power
this board, I connect it to my modular synth's power supply. I have a
+-15V in there and a power distribution board that has the 0.156"
headers (like MOTM). I made a cable that has 4 banana plugs on one end
and a 4-pin 0.156" connector on the other. this power's my breadboard.
if you had a bench PSU, then you don't even need to make that special
cable because they usually have banana jacks on them.
if you really want to be cheap. there are supplies like this:

A 400ma linear +-15V supply. but if you are new to electronics, this can
be pretty dangerous to wire up. So, if that is you, I cannot reccomend
it. Ok, so if you are unsure about this, take that comment very
seriously, but I had successfully wired my own PSU to the wall very
early on in my synth building.
you might be able to find an already enclosed power supply. a linear
+-15V would be nice. 400mA is probably the minimum. That is low for a
modular, but plenty for testing individual, or even a few modules. this
would probably be cheaper than a bench supply.
the board you mentioned is pretty neat. but I agree with Adam, I don't
think you will use much of it too often. For function generators, you'll
probably have a VCO anyway.
I do like the idea of having a complete development platform for synths.
I always imagined building a special breadboard that had pots and jacks
built on so that I could test modules quickly. I have not gotten around
to making something like this yet.
