New house alarm - Perth area

[signo3d`]

Hi guys,
Have been reading the forum for a while but now decided it was time to speak up lol
I'd like to replace my old alarm (3 pir) with a newer one and add a perimeter alarm as well.
I will roughly need 10 reeds/gbd + the existing 3 pir will be replaced (hopefully using the original cables)
Everything is going to be hardwired and a 4th pir will be installed in the garage.

I had a quote for just under 3k for the honeywell vista 12 + tuxedo touch pad, and another quote for 2.5k for the risco lightsys 2.

Any opinions on the 2 system? I was hoping to also get a quote on the bosch system (3000 or 6000) but i have not found a bosch supplier/installer yet (Perth metro area).
The fact is I cant really find information on these systems (the Risco and the Honeywell))....does that mean they all are pretty much good....or the opposite lol??
Thank you!
