Has anyone used one of these? I've been comparing this 25.4 cc blower with a 25.4 cc blower from Echo. The Ryobi is lighter. 11.75 pounds vs 14.5 pounds. Several other advantages. Better air-cooling of your back. Cheaper cost. The disadvantage I've seen so far is that Echo offers a complete parts list on their web site, Ryobi does not. The parts list shows the backpack parts, but not the engine parts!! Also, should I need to buy parts for the Ryobi, I know I will be able to get them for Echo, from merchants selling on the internet; for Ryobi, I'm not so sure. Has anyone had any experience with the Ryobi, or getting parts for it? I much prefer to order over the net, rather than take the bus to my local dealer. Their parts manual, tho it was on their web site, was hard to find. You were forced to try and figure out which item was the parts manual, from abbreviated filenames, in a simple directory listing of filenames. That's the best they could do for a listing of avaible owners manuals and parts lists. What a bonehead way to list things on a web page! But the thing is lighter, and cheaper, yet has the same cc's.
