I added the price in US Dollars:
I'll put the prices in Brazilian Real, but just for comparison between them.
PB-3000: R$ 9400 1400
PB-2000: R$ 6700 800
Klipsch: R$ 6300 750
I don't know how much this matters, but looking at relative costs for you vs costs in the US, the PBB3000 is a deal!
The way I am looking at it is in the US, the PB-3000 costs 75% more than the PB-2000.
In Brazil, the PB-3000 costs only about 40% more than the PB-2000.
I guess that makes sense because if the shipping cost were, say, something like 2500 for each, the difference between 4200 and 6900 is getting close to the 75% difference!
