I know this has been run into the ground. I will purchase one of these two soon. I have run the echo 750 and was impressed, but i have not run the redmax. It would seem based on the specs that the 7001 would have to be much stronger 7001 - 730 CFM @204mph 750 - 625 CFM @ 201mph In some of the threads some of you say the echo is a little stronger. How is this?
