If you go into a store to buy a beautiful shiny machine, you will find some very nice models, but with very high prices. So, my question to you is this, which model is best for you?

The first consideration is the manufacturer. Who has the product must be mainstream. They had to have been around for a while. Their quality must be demonstrated. Check references such as Consumer Reports, on which they recommend. You have to see if the unit value of your money.
