anybody have any comments, good or bad about the shindaiwa t-230? Always used stihl in the past, new dealer carries shindaiwa. no stihl. My brother loves the t-27s, but has no experience with the smaller machine. also looking at the shin 630 backpack, because of the higher cfm's and mph. The comfort of the stihls(backpacks) might be missed. Also does anyone know if redmax still has the vents for your back on their blowers, and if so are they worth a shirt?
