Exactly. Like many things, it's a value-of-time juggle.
Anyone can do the job, and do it right, but... how much time do you want to spend learning versus riding.
I feel neutral on the fact that I took my R90 heads and transmission to a shop, because while I have the tools (and probably half the experience/knowledge) to do it myself in my shop; it was done right the first time, and fast. I can live with that.
