I had a Liftmaster LA400 that I hadn't even purchased from GateCrafters and told Tony this when I reached him for tech support over the weekend. I would have paid a good deal to get help. He looked at my pics and questions and with some work on my part, I got the unit up and running. I have now purchased some additional parts from them and will be a good customer They also have sales people and you can't get anything close like their tech support and knowledge. Tony went way above and beyond to help me like a good samaritan and I am grateful for that.
