I have a Ryobi hand-held leaf blower/shredder, which works fine, but...

- The shredder bag is way too small (have to empty it too often)
- After running it for half-an-hour or so, my arms are aching :-)

So, I was looking for a bakpackstyle blower, but have NOT found one which is
also a shredder, with a collecting bag. I'm pretty sure I've seen them out
there, but no store in this area carries them. Any ideas?
