I can think of a few reasons real quick on why to spend the extra cash on a ham radio for 11m:
1. No CB/Export radio can come close the the RX on a radio like the 706. If you're really into DX'ing, often the RX is more important than TX.
2. If you have antenna restrictions where you can't put up big directional antennas like yagis, then RX sensitivity and configurability (filter shape, pass band width and range, pre-amp, attenuator, etc.) is even more important.
3. Speech compressor function on most ham radios can make a big difference in "punch" in TX. If it's still not enough power, you can always add more.
4. If you want to listen to aircraft, short wave, ham, military, you can without buying another radio.
That's my two cents.
