First off, if someone posts here on AS about a 30cc "homeowner" saw (as I have), the discussion will drift to more cc's and bigger and better, until you wind up with the 361 and 5100s. This is an example of the relative constant that I call "The AS Chainsaw Drift". Its is like the red shift of light in the expanding universe. No matter what you think you want, you really need and want either a 5100s or an MS361. No two ways about it.
Secondly, walk into a logger area Stihl shop unshaven in Levis, flannel shirt, cork boots, a 'hat head', and they steer you toward the pro end of the linup or ask you what you broke on your 460 Mag. Then go outside, change clothes and shave, walk back into the same store with clean shoes, creased slacks, a white shirt with open buttons (like you just pulled off your tie) and they will steer you toward the baby saws or ask you if you would consider hiring a pro instead of buying something as dangerous as a chainsaw. That is, if they even notice that you are in the store. This is an example of the chainsaw homeowner-pro paradigm. Seemingly there are no people in between these two extremes. The same with the saws. They are either flimsy throw-away homeowner models, or they are souped up pro models. There simply are no mid-range sawyers, and there are no mid-range saws.
To exemplify the homeowner-pro paradigm, I have these two photos. This first one is of a typical homeowner saw (Echo CS-305) and typical geeky homeowner using it (under professional supervision, of course):
This second photo is the typical professional saw (fully modded hotsaw) and typical professional sawyer (don't try this at home!):
