Like I have said before on this subject, price is not always going to mean a unit will last.
So many years ago I can not remember exactly, bought a $60 electric at Harbor Frieght.
Was just to have a back up for our Tech Center Training area.
Our Auto Processing Division had high dollar, professional units, but they would go down due to be used 8 hours a day, 5 days a week.
The manager would come over and borrow the little HF unit for a week or so at a time.
(I owned the unit, it was not company owned)
In Sept of 2008 I retired and brought the little cheap sucker with me and it has been used for hours on end, without a break.
I use to clean the siding, to clean the driveway, etc, etc, plus blowing the wheel wells and wheels on my vehicles.
Was worried that it may blow up due to the price and the hours and hours it had been run, so when the local Aldi store was running an electric unit for $70 bucks, bought it.
Only used it twice, still run the HF unit today.
I think it is about 7 years old and still going strong other than having to fix the plug on the cord once.
My point is this, price is not always the determining factor for quality.
