While others have relayed many horror stories with the big mail order stores, I've had great experience with ComDaC. Since getting my tech ticket 2.5 years ago, I started dealing with Duane and Barb at ComDaC in St. Joe Michigan for most of my gear (
www.comdac.com). Recently I upgraded to my General and had many questions regarding my antenna selection and installations. Duane was extremely helpful and willing throughout this process. This has been through both email (prompt responses) and phone calls.
With my recent purchases for a random wire antenna setup (AH-4 tuner, etc.), Duane also included in the box some additional notes to help with the installation. Everything with this transaction and past ones (mobile rigs, other antennas), he has gone above and beyond good service.
Since I live in Michigan, I do have to pay sales tax on my purchases that could be avoided if I delt with other suppliers. For great, honest service, it is a small price to pay.
By the way, I have no financial ties to ComDaC other then being a very satisfied customer.
