You have all that DIY too, except maybe shock bills, but it's your problem to fix. Like with everything, extremes are bad and all managed or all unmanaged are both bad. My personal guideline is use off-the-shelf services if they are cheaper than DIY, including labor, or if DIY provides no competitive advantage and off-the-shelf is cheap enough. But if DIY is much cheaper or gives a competitive advantage, do it yourself.
