The essential argument is don’t cheap out and get something of lower quality just to save a few bucks, in the long run spending the extra $$ will save you a lot of heart ache and stress. I can personally relate because of how frugal I can be at times, very often I am tempted to save that extra $10 only to be disappointed with my purchase down the road.
