I had picked up the 1900 used from another member here on retech and it wasn't working properly from the get go. I contacted the member and he didn't hesitate to tell me to send the motor back to him so he could send it back to Tekin for warranty and then send back to me. He sent me a pm a couple days ago saying Tekin was sending the motor back to him and when he got it he would send back to me. So now I just wait patiently for the 1900 to arrive but with a perfectly working 2050 I haven't skipped a beat. Plus I have my SC8e set to arrive tomorrow and have a bunch of new goodies here at my house waiting to install in it! That's gonna be a bitchin truck!!
