The way I see it there is a price/value curve where it's worth buying things at both ends.
At the high end you're paying a premium but you're getting a well designed and constructed item, which should last you a long time.
At the low end you're buying cheap crap but you're paying peanuts. You know there's no high end features, that it's not well made and if it breaks you just throw it out.
But in the middle you're paying more than the cheap stuff but you're mostly still getting crap, although here's it's likely to be 'branded' crap. Same thing as the cheap stuff, just more expensive.
So buy at both ends of the scale, not in the middle: buy cheap and get what value you can out of it, buy expensive and appreciate its value for a long time.
