I am in the market for an aerator and I am going to demo a Plugr by rock solid on tuesday. I have heard that they are good on flat ground but on hills they are trouble. I am looking for a machine that is easy to operate and dependable. There are alot of machines out there and not many prices on the internet. I am looking to spend not much more than 3000.00. Is that possible? Anyways I guess what I am looking for is some prices on some of the more popular models. I kind of prefer a walk behind so as to not tie up my Tiger. I prefer to have a separate machine so I could go and do aeration jobs and not interfere with my lawn mowing. If I have to I will use my walk behind mower as a last resort to not spend more. What is story the on the jrco unit? Is it any good? Any info would be great> Thanks Bill BY THE WAY I AM NOT LOOKING TO START A BRAND WAR!!!
