I bought a new 2007 RedMax EBZ7001 backpack blower to replace the old EBZ4800. The old blower was bought about 3 years ago, but the piston got worn out and to many related parts needed to be replaced that it wasn't worth fixing. Damage wasn't caused by abuse or poor upkeep, just regular wear and tear. It was my first commercial tool and blower. This new blower is real nice, powerful and not heavy. It has many of the features thats on my larger RedMax EBZ8000 backpack blower and weighs less. Cost $499 + Tax at my dealer.
