I'd like to buy a handheld blower. I've narrowed my choices to 3: Echo PB230LN 160 mph, 365 cfm at the pipe, 410 cfm in the housing. Redmax 2600 160 mph, 367 cfm Stihl BG85 183 mph, 459 cfm. I'm not sure if the ratings for the Redmax and Stihl are at the pipe or in the housing. Prices are the same for all 3. I believe Echo and Redmax carry 2 year warranties, Stihl a 1 year warranty. I know the Echo and Redmax engines are commercial grade...not sure about the 27 cc engine on the Stihl. What has been people's experiences with any of the 3 models. What would you reccomend? Blower is to be for a father's day gift for my dad. He'll be using it on his property only. It's not that big so a backpack is not necessary. I don't want to buy the cheaper residential version of each model. Just looking for the biggest bang for the buck.
