"I'm not rich enough to buy cheap things" - - No idea of the source, but I've come to appreciate it's wisdom over the years. Whenever I compromise on what I know what I want and make a decision based on cost, I quickly regret it and end up getting the one I knew was the right one in the first place. Also, as I get older, my tolerance for cheap crap has been diminishing rapidly. Life's too short to deal with cheap garbage.
So, I'd rather go without something then deal with a crappy product. If I've gone through the (extensive) questioning phase and determined that yes, I would really need/like to have something, I research to find out what is the one that is the best value that meets my criteria, and wait until I can afford it.
This works as you'd expect for "lifetime" purchases, but it even works (if careful) for shorter-term needs, because you can usually resell the item in question, making the overall cost lower.
An example is Apple computers. Yep, they're more expensive up front, but they are (for me) much more enjoyable to use and actually have resale value after a few years.
Everybody likes to state that the hallmark of capitalism is that you can buy the best product at the cheapest price because of competition. My view is somewhat the opposite, that you end up buying the crappiest product they can convince you to purchase for the highest possible price, due to marketing, artificial monopolies, etc. :)
