Oscilloscope DL1620/DL1640/DL1640L

Hi all,

I'm planning to buy a DL1620/DL1640/DL1640L CRO for my Power Quality application.

Can anyone get me the pricing for this yokogawa oscilloscope.
Also can anybody suggest me any other better/cheaper alternative.

Guys.....these oscilloscope claims that it is having CAN bus signal analysis function. I will be using CAN for one of my interface. But i'm new to CAN.
So what exactly is this signal analysis for CAN??

So i need:
1. Pricing for oscilloscope
2. Better Alternative.
3. CAN bus signal analysis

Kindly help me out.
Thanking you
