Very true...
however if you live in the US or Canada you won't be able to use the #g stuff from the V3x anyway...
The main advantage I can see in the K1 is the QuadBand option . Again in the US/Canada you are going to notice difference... huge difference in quality of reception if you have the 850/1900 vs 1900 only...
Bare in mind that K1 is almost double the price of the V3x, so if price is an issue .... V3x would be the choice.
my 2 cents.
