Both of those are very nice and will certainly do the job. Do you think you will m/l hunt alot or a little after that trip? Reason I ask...there are alot of m/l that will do the job out to 200yds with no problem, that are relatively inexpensive if it will be an every now and then thing.
I personally love Knights. In addition to the mountaineer, you could look at a bighorn, mk-85 (great older gun), and many others. They even have the wolverines back in stock at Knight for a limited time and they are quite inexpensive.
CVA also makes some nice guns, and they aren't too hard on the wallet either.
Heck, a used gun (in great shape) is a very good option too.
