It's been quite a few years since I put in my last system and planning to add a building with expander. Have the panel and keypad but need wire, door sensors, motions, and maybe glass break. Lot's of places out there on the net but looking for a few pointers on who is good quality and price. Before anyone says it - I realize I am not going to get the best quality at the lowest price. Just looking for good quality and good price. I can obviously look at ratings on amazon and ebay and have done some of that...
