WY antelope is the gateway drug to western hunting. The buck tags are pretty cheap (~$270) and doe tags are dirt cheap ($38-50). There are decent bucks in every unit, preference points and harder to draw units generally provide better public land access, but even a 'poor' unit like I hunted the past two years has decent opportunity if you are willing to walk further than the next guy.
I had this guy and a doe quartered and into my pack by 11am opening morning after a 3 mile hike from the nearest public road.
Assuming you don't need any gear and are equipped to camp, you can do a WY antelope trip for a few hundred bucks. Driving from Chicago and splitting gas 2-3 ways it's cost me about $600 all together including tags (1 buck 1 doe), gas, food, etc.
Nice buck! Have a couple of those from years past. Now just like the meat. Between my hunting buddy & I we bring back 4 does, which gives us and my kids each an animal. With our KY deer the freezer looks pretty good! Would like a mulie in the future. What are the chances in Montana for a NR?
