I am buying an aerator in Spring '08. What's your vote for the best one? I don't like the Plugr, so it's not listed here, if you must vote for it, vote for other. I have WB hydro mowers, so a pull-behind or JRCO is also not listed. I will take your votes into consideration when buying, thanks! At this time, I'm leaning to the Classen split-drive, or the Ryan.
