I think you suffer too much for 700 dollar. In life you have to do a lot of shopping, a car, a house much bigger and you do not know how it will work either. +
For example a car can give problems from the first day and although there are guarantees you can touch a problematic car. The insurance of a car at all risk costs more or less $ 700 and in many years you will not even use it.
Or when you buy a house on a plan that is not yet built. Will you die of stress? You have to have more calm and more for innovative products that involve research.
