Im not trying to start anything here but If you just check Speed Passion Direct prices, you can pick up a brand new esc for less than he is asking, Granted he has a program box, but those can be had for cheap as well. I would personally look at the new Reventon series, If you are only ever planning to run 13.5/17.5 with no boost the Reventon S can be had for $45 or so brand new, or if you ever plan to upgrade to mod or want to try boost out the Reventon R is only $61.... The R at least comes with a program box and can also be plugged into your computer for fine tuning..
