Gary aerators are sure a difficult thing to shop for. I have also wanted a better one than I have yet find when I look they seem to jump from inexpensive $200-300 ones to well over 1k. I never have figured out why. For the twice a year I run one for 4 or 5 hours over 1.5 acres of yard I just will not spend 1k to 2k.
The one you linked looks to be better made than the one I have although it is the same design. It looks to have a better axle with bearings and grease fittings as well as heavier gauge steel. Mine is a Brinley sold a Home Depot and several other box type stores. It also seems to be sold under some other names. To be honest I did not have high hopes for it’s longevity. Surprisingly it does a decent job of pulling 2-3” plugs in my red clay IF I wait for a high moisture content in the soil. This morning I took advantage of the damp soil Fay left us with so it has completed it’s third year of use.
I just throw this out as food for thought. The Turfvent looks to be a better built unit than the one I am using and will most likely last longer. It does not look like it will pull deeper plugs. I could also buy 3 of the ones I have, at the price I paid, for the price of the one you are looking at.
