I usually do a lot of research and buy a model that I feel will give me good value for what I paid new, AND have resale value if/when (more when than if) I decide to upgrade. If you buy a "throw away" player, then it's less likely to satisfy you in the meantime and have little or no resale value. My old Sony 560D served me well for years, but had little resale value, so I gave it to my daugher and it is still seeing duty in her bedroom.
