Our new shack is prewired for a security system and I'm ready to get it all wired up. I installed a DSC 3000 in our house in Houston about 16 years ago. It was easy to install and worked great. Just wondering if anyone knows of good places to buy controls, switches, keypads, etc. at good prices. I know that there are some pretty trick keypads around these days. What's the best bang for the buck? Thanks!
