I just remembered one other thing re "trialling".
In Australia Bose does not have the 45 day trial (at least not when we bought it about 6-8 months ago now) but the store we bought it from had a loaner/demo model. We grabbed that for 1 week, setting it up at home in the lounge (something I recommend) to learn the system. Then we played 3 gigs with it oif I recall, at pretty different venues. By the third gig we knew it was a keeper.
That sounds like a sensational price btw - but what exactly are you getting?
We got a Model 2, a T1 (Bose mixing desk) and 2 B1 (bass modules) for approx $4990 (Aus)
