Dude that is an investment in your health and well being. Put the cheapie back in the box and get you one that attaches to the front of your mower/tractor that you cut the yard with and have the best of both worlds for the rest of your life.
Look at it like buying a mattress. Folks say, OMG you paid 1K for a mattress and I said yep, do the math over 10, 15, or 20 years and see what you pay per night for a good nights sleep. Same with good yard/grounds upkeep equipment, buy a really good one one time and be done with it. JMHO,
