For string trimmers anyway ... I was at a local dealer last week and I was comparing a Maruyama BC2321 to a RedMax BCZ2301S. I immediately noticed the RedMax being longer; so to make absolutely sure, I emailed Maruyama last night. Being that the BC2621CA would be the trimmer I'd get if I was going Maruyama, I asked them what the tube length is on that trimmer. They wrote back and said 57.1 inches. (RedMax is 59 inches). My conclusion? I'm sure Maruyama is a VERY high quality trimmer, but I need that extra 2 inches.
