I don't have a problem with anyone asking questions, homeowner or not. I'm so ignorant of many things involved in landscaping, for instance, it isn't even funny. None of us can know everything.
However, the old adage of using the right tool for the job comes to mind. No one wants to spend more money than they have to, but anyone, business owner, or homeowner, should consider the long term costs and benefits when purchasing equipment. Herler gets off on a tangent at times, but he also makes some valid points. The guy's wife doesn't understand power equipment, but probably wouldn't hesitate to spend $500 on some pretty doo-dad to hang on the wall in the house. Anyone male on here that is married should be able to relate to that scenario.
Simply put, are you going to go cheap and dread the drudgery of blowing the leaves every fall, or buy top of the line and make it a somewhat enjoyable chore? No more than the average homeowner is going to use a commercial blower, they should basically last forever.
