I have a dealer that has BCZ3000s for $349,

1) Is this good price?

2) BCZ3000s was a new model and someone said it has some pinging noise from the piston, has it since been fixed? Any problem with this trimmer?

3) How loud are these two trimmer, are they as loud as the ordinary 2 cycle or they are quieter?

4) How does this measure up with Stihl FS 110, FS130 or Shindaiwa T272 and T3410 and Honda HHT35

Thanks
