Well, I did some more searching and found a NIB Win 94 BB for $299. For that price, I can't go wrong. Here's what convinced me to buy one( And I'll preface this by saying that I've never laid hands on one, so I don't really know how it will "feel"):
1) Only "reasonably-price" big bore I could find w/full-length mag tube.
2) 2 more rounds in the tube and only 1" longer and 0.5 lbs heavier than my Marlin GG.
3) Beefier receiver (50K vs 40K psu on the GG).
4) Paco Kelly calls the Winchester Big Bore 444 his favorite levergun.
5) $299!
Of course, after all is said and done, I might take it out and shoot it and hate the dang thing. We'll see I guess. I'll let everyone know. Nothing wrong with the GG, I just want a more classic-looking big bore.
