I needed to replace a split boom shindaiwa power unit, so I found a unit called Swisher made by shindaiwa. I searched and searched to find out if these units were any good since they were really cheap on Ebay or Amazon. I read reviews on Amazon and they were mostly 5 star, so I took a chance. I received the unit earlier last week. It seems to be the same unit as Shindaiwa T254. Starts and runs well. It was only $160 on Ebay. The T254 is $325 plus shipping. Shindaiwa provides warranty on these units. I think it is a real bargain.
