If it is something that I wish for it to last, I find it best to opt for a reputable builder. Someone with honest references. Not shady.
If it is something that I can build and rebuild, as it will break or wear down, without it sending me to hell and back, then I will do it myself.
Mind you, everyone has their own pathways to what they need. Some of these pathways include a basket of spicy chicken wings and cold ale.
