Hi All, What's your "money's no object" dream shotgun and how is it different from the Remmington 870 that's on sale at my local gun shop?

I've never hunted w/shotgun before, so I'm in need of advice. I'd like to buy a combo, for deer & turkey. Anything I should look out for as good or bad?

Also, after bow & rifle hunting I'm nervous that a slug is gonna just blow the hell outta the brisket... true?

Anyway I find that every time I spend the least amount on something I'm trying for the first time, I end up wishing I'd spent a bit more for something better one year later! Trying to avoid that this time....
Thanks!
