Howas are generally good actions. The quality is up there with most major brands. Granted, most people use Remington 700 actions to customize their rifles, but you certainly can't go wrong with a Howa action (or barrelled action).
I too have a strong preference for stainless, and a .35 Whelen. In fact, I too have been considering a Howa barrelled action as well. :grin:
