I'll agree the Tactical isn't worth the extra $700... but if money is no object it sure does look bad ass!
I totally agree about the scope as well. You gotta be able to see it to hit it.
Nothing wrong with any of the rifles listed here IMO, they all shoot roughly the same as far as accuracy and are good quality. Personal preference is what really counts in the end, so I say shoot as many different ones as possible, but make sure you go and fondle all of them and see which one jumps out at you while you hold it (just like choosing a pistol!), and cycle the action, safety etc. I feel a removable clip is really nice to have as well but it's something a lot of people forget about until they're in the field having to unload their shells all the time when they climb a fence or whatever the case.
Actually I'm surprised no one has mentioned the Savage Predator yet. My buddy has one and it is a fantastic shooter as well, especially for under $700, complete with accu trigger-- good value for the money.
