The ultimate solution would be to build it yourself! 

[![enter image description here][1]][1]

Arduino has an excellent step by step guide on how to build a [standalone Arduino][2], using a ATMega328, on a breadboard. Now everything is removable, not just the chip.

Note that there is one slight error in the guide, which I have highlighted here, [Arduino Standalone - photo shows incorrect pin wired to MOSI][3].

There is a video on how to achieve, more or less, the same thing, [1-Day Project: Build Your Own Arduino Uno for $5][4].
