Just make your own. It is a very simple project and the parts are easily available and cheap.
Did a quick google search for a tutorial (pictures are infinitely easier to understand than me describing it, after all).

It uses the same parts that I would choose and is well explained. You don't have to make your own PCB. You can get predrilled, ready to use boards in various sizes. Generally referred to as perfboard.
If you want to avoid soldering completely (although it is very easy), you could even use breadboard (solderless prototyping board). You can get some pretty small ones very cheaply. Just stick in your components an give each a "leg" a little drop of hot glue to keep it in place.
Since every part except the potentiometer (which you will likely not put on the PCB anyway) is solid state and doesn't produce any heat to speak of, this method should work just fine.
