I was gonna say my hands also...nothing is as precise or has lasted longer. They clean up well, and repair themselves when you damage them. Planter, weeder, bug picker, harvester, broadcaster, and diggers.
Stehl (sp?) rototiller. It's a little heavier than a mantis, but easier to control. I also love my Garden Way seeder. Right now my ground is too rocky to use it, but I am working on them. Working and working and working. Those stones just keep coming.
