We ran a few of the blowers that were the same as echo 755t I think the shindaiwa model was 633rt but they were same exact unit other than red in color and 60.00 cheaper a unit. Also echo has fleet deals if you can buy 10 units at a time save lots of $$$ and they can be all different types ie 2 blowers 4 trimmers 2 hedge 2 pole. I get together with a friend when I dont need 10 and split 5ea. The only problem we ever have with the echo is muffler screen clogs (after a few years)we just remove them. good luck on your choice.
