I've purchased from uncle Kevy and so have a few friends of my own. He's been in it for the long game for a long time and knows you're not going to pull the wool over on anyone and they simply want to sell people good products. Whether you like them or not, he knows his business and how to work with customers if you are serious about buying something for a new system, or upgrading your system.
It's worth doing a little research online about something before you call, and if you start telling him about this person said "this or that", he's the type of person who will tell you to go buy from them instead if that's better for you. Simply put, you either take his recommendations or you don't. He's been around a good long time.
