I'm a mix of both. Sometimes I will buy the most expensive item, but I usually do that when it's the best item on the market. I will buy cheap items if they usually work fine and get the job done. Build quality will sometimes go down when you buy cheap stuff, but the higher priced items tend to be of better quality and presented better.
But, some cheap stuff works fine still, so it's not always a bad thing to buy cheap. Some expensive items are also overpriced, you need to consider that too.
