Radio Shack sells a number of little experimenter circuit boards. Here is one for $2.

They sell several types. They make a board with the identical trace patterns as their little breadboards too.

I use this one all the time. You can use half of it and cut it to length if you want smaller.

And a small one - perfect for a little LM386 circuit or something
