Bounty $20 +$140: What Binoculars to buy for trip to Yellowstone?

I am going to Yellowstone in a week and I need binoculars. My problem is i have no clue what to even look for in these type of products.

I will pay $20 in SBD bounties to useful answers for me. I will also use all my voting power which will distribute about $72 more to useful answers on two days.

I travel often and so I want nice ones that last me for a long time and make me feel like I have a very good quality product. Price is really secondary to me. I want to buy a product that last me as long as possible and is the best that I can get.

I like to go on trips to see animals and things like this and will need one anyway for safaris etc. These trips are usually a ton of money so saving on gear tends to not be something I do.

My first question is:

1. What is a an appropriate price range to look for. I see ones that cost a few hundred $ and ones that cost between $1k and $2k. Is there a real difference in picture quality between these two or better zoom functionality or is the difference simply the image stabilization etc. If there is I will want to more expensive version. Examples for cheap version: https://www.amazon.com/dp/B016OK3MK4?psc=1 Example for expensive version: https://www.amazon.com/Canon-Stabilization-All-Weather-Binoculars-Batteries/dp/B00004THDE/ref=sr_1_3?s=electronics&ie=UTF8&qid=1503276949&sr=1-3&keywords=canon+binoculars

2. If the answer is: get the expensive ones I see that canon just released new ones that will come out in November. Are these better than the ones on the market, in which case i would gladly wait and simply rent some for this trip. http://www.canonrumors.com/canon-unveils-new-binoculars-featuring-enhanced-image-stabilization-technologies/

3. What are the important specs and especially what describes the zoom etc. In general what are the specs to look for in good ones. Again I have no idea how these things work, all i know is that on my last safari the ones the guide had really sucked, and next time I want my own. I would love if someone could explain to me how this all works and what to look for.

I am leaving on Friday and will want to make a buying decision on Monday or Tuesday. I will reward any answer that helps me make a buying decision this includes description as well as links to youtube videos or articles that will be helpful. Ultimately I am looking for an actual reference to a product to buy and an understanding why this is the best possible choice.
