I personnally don't think you could go wrong with the Remmy. I own both an 1100 and 1187 and have had minimal issues (replacing O-ring and the 1187 shell catch depinned)
Neither one is my go to gun for waterfowl or upland anymore, but they are solid firearms.
At least with the 1187 there are an abundance of gunsmiths knowledgeable on the repair and the parts are re
adily available.
I've heard good reviews for the Weatherby, but have never shot one.
My recommendation is shoot what fits the best and I wouldn't count out the used shotgun rack. You might be able to get into a Gold/SBE for not much more than that price.
Hope this helps
