I've seen these for years, available in every country EXCEPT the US, but finally Maruyama has them available for the US. For large trimming jobs, like spending an hour+ in a HOA lugging a trimmer around, burning your arm, killing your back, I think a backpack mounted engine would be a pretty slick way to go!
Cons I see are the lack of being able to flip it upside down to edge, and possibly your reach under low trees and bushes...
If you have a Maruyama dealer I'm sure you can order one, but here's a few listed on Ebay http://www.ebay.com/itm/251226095971?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
Seems pretty slick for guys that have a lot of straight trimming to do, and they support a brush cutter head as well.
