AIS Class B Transponder: Worth it?

Wondering if the Class B transponder rather than a dual channel receiver is worth the extra $$ and the extra power draw is really worth it. We are preparing for a classic Atlantic circle and then, next time around, into the Med for 3 to 4 years.

1) I know the motto is see and be seen but has anyone with a Class B transponder really had the bridge of a big boat call them?

2) Won't carefully set guard zones and alarms (even with the false alarms) be more effective than assuming a tanker doing 15K is going to call me doing 4?

3) Am I missing something that makes the extra power consumption really worth while (about 20 percent of our total daily consumption for Class B transponder compared to 8 percent for a receiver only).

Many thanks for helping me sort this out,

Jay
