Just ordered my Echo 770 a minute ago. In 3-5 days I'll have my own review up. I absolutely cannot wait. I wanted a redmax blower for so long after using one, but now I'm glad I went with the Echo.
I know their reliability. I have had my Echo pb403t (blower) and srm210 (trimmer) since 2004. The blower is still my primary (and runs strong) until the 770 gets here. The trimmer still runs strong but I replaced it with a redmax only because it was way lighter.
