I'll definitly agree with that. the only thing I do to my own equipment in general is change the oil, clean air filter, change oil filter, replace spark plug, change hydro oil, change hydro filter and greasings, oh and tire pressure and sharpen blades. anything else and I mean anything goes into the shop. mowers, trimmers, edgers, blowers, etc. my kombi motor had been in the shop 3 times this season and my trimmer is on its second visit. for some reason this is the year of repairs for me.
