EVO spec king 2.5- adjustor or not?

I'm about to pull the trigger on the evo spec king 2.5's after finding out I'll have to buy longer rear shocks anyway. I'm trying to figure out if the adjuster is worth another $400? Anyone have experience with both? Not having it saves money, 4 less things to fiddle with, and with snow and salt, less stuff to seize up. On the other hand, having adjustable suspension might be worth having.

Don't have the Kings - I've got Fox's with the adjusters. I personally like the adjusters, especially when you are loaded down. Being able to tailor your ride is handy.
