Leaf Blowers

I'm not sure if this is typical Husqvara quality of their "homeowners" series but I am not impressed.  I've had the Husqvarna 125BV blower vac for about 2 years now and it already needs a second new muffler and a second new impeller.  I've already replaced both once.

the first time I got burned by the melting plastic guard in front of the muffler.  The muffler had broke off exactly like the second one now had and bumped up against the plastic melting it.  

When I tried to replace the muffler the first time, the two bolts were extremely difficult to remove and when they did come out it was obvious they brought some of the aluminum threads from the head with them and I had to clean that off the bolts before I could get them back in.  

The replacement I had to install at teh beginning of this season is also in bad shape again, with many broken blades.  While it does suck up some small pieces of mulch fragments, I'd assume the blades are built for more then just leaves and can take it.  I don't abuse it and can't understand how this is happening.

So to sum it up, burned by melting plastic muffler guard, needs a second replacement muffler, Muffler bolts are stripping out the head threads, need a second impeller replacement.

Should I consider a different brand?
