Just came across these yesterday. Its out of my price range but considering its 1) switch 2)motor 3) decoder all in one its still expensive but not to crazy expensive. The cost of a peco switch, tortise and wabbit is about 55 dollars. the flea is 83 dollars. like I say to expensive for me but neat idea and maybe some day the price will come down.
