I went to this store with ZERO idea what I was after. I had a few pieces of a system which my uncle bought second hand, and some very specific requirements in mind.
The staff here helped me in simple terms and ended up selling me a device I would never have considered, it suits all our needs and they were helpful enough to break it all down and help me draw a diagram which details exactly what to plug in where.
This happened over a year ago and the system still runs perfectly. Thanks guys
