Folks,

Update on the drama with my system. The company has agreed to replace
the DSC pirs with Bosch Tritech units (They also call them blue line).
The bad news ... they cost a lot more. Even if they are not charging
me labour, its still working out to an additional AUD$660, thats 6
units in total. As expected, the family are not supporting me on this
one.  Yes, I did complain and kick up a fuss, but they are standing
firm on the fact that they are only charging me the difference in the
cost of my originals and the new units.  What I can't figure out is,
pirs in general seem to cost a lot more here in Aus than say in the US
or UK. I took a look at Bass's online store ... for 6 units, without
shipping, it's still only a third of what I am spending here. I have
called around a few other local companies, and they are all charging
way above US rates, in fact the cost I got from my installer is
cheap ... hmmm, maybe I should get them shipped from the US!!
