I purchased a Duel Aer 2475 this spring and I loved how easy it was to maneuver. I think it is the most well-built aerator I have ever owned. I did have some issues with the unit. David, the owner of Stinger, went to considerable effort to make sure I had a well functioning unit for the fall aeration season. I think their customer service is amazing and I will definitely be watching what else Stinger comes out with.
