I was looking at Tanaka's edger today at my dealer. It looks like a REAL quality machine. I'm wanting to buy a WB edger. I'd go for the Tanaka, but am a bit concerned about engine longevity because it's a 2-stroke. I can get a McLane, etc WB with a 4 or 5 HP Honda 4-stroke for roughly the same price. I don't doubt the Tanaka has enough power, but If the 4-stroke will last longer I'd rather purchase that. What do you guys think?
