Cheaper is not always better. When I was younger, I would always seek out the cheapest version of an item because I was broke and that was what I could afford at the time; however, this actually ended up costing me more money in the long run. Generally, the least expensive item is also the cheapest item (cheapest made using the cheapest materials) and needs to be replaced soon. When you are shopping for a specific item, find something that is the best quality item at the most reasonable price, do your investigating before laying out the cash. If an item is too expensive, figure out if you can make do with something else until you save up enough cash to pay for it.
