Which Decoder Should I Pick?

[tompm]

There seems to be an overwhelming amount of information and decoders to choose from and at times my brain feels like it is going to expose. However, reading the responses and following them I am getting something of a better understanding. Electronics and electrical things are not my forte but this is helping and I ask for you to keep the information coming. I am a real novice at this and need all the help and reassurance that can be provided.
