There are many options to choose from, and special considerations for each. So how do you know if you are getting a deal or getting robbed? Find a Specialist. First and most importantly, hedge your bet by buying from a reputable vendor. When you buy from Amazon, eBay, or Craigslist, you might get a quality product, or you might not.
These companies just provide a way for individuals to sell their products to large audiences, so it can be a risky purchase, depending on the nature of the seller. Even if the listing specifies all of the best components, you are relying on the seller’s honesty to get a quality product.
