I have used Horizon service in Champaign IL many times over the years and have always had good service. Less than two weeks turnaround counting a couple days shipping on both ends (I am pretty close so UPS ground gets there in one day usually). My JR DS 8411 servos have been in there a couple times each due to worn out pots and/or gear sets. I am not happy with the servos, but the service has been good.
