Always delay buying a high-tech device, like a car, TV, DMM ... as long as possible. And make sure you have thoroughly investigated your actual need and specification for the item, and get to know all the leading products in a particular range. You will then find that one product will suddenly click and seem just right for you. At that stage you need to talk to the actual users of the item to get the real story. With scopes that would be some of the members on EEV (the reason I joined EEV a few years ago).
To illustrate the point, when I was last looking for a new car, I narrowed the choice down to about five models. I read the reviews checked the performance, the insurance costs, and the servicing costs and finally arrived at the model that seemed just right for me.
A few days later I saw the same model parked at a taxi rank, so I asked the driver what he thought of the car. His response surprised me. He said that it was a piece of *%$#@ junk and had a major problem with a part of the engine that costs a fortune to fix. He also said that the car was noisy on the motorway and uncomfortable. He said that he would be getting rid of it soon. I was rather deflated by this so asked around some more, but sure enough, the taxi driver's opinion was reflected. Naturally, I didn't buy that type of car.
Why did I say to delay as long as possible? The fundamental reason is that with high-tech products the performance keeps improving and the price keeps dropping. Not only that, but today's red-hot product will be available on the second hand market for a much reduced price within a year or so. Of course, you can take this philosophy to the extreme and never buy anything (I still havent got a new car).
