Neo-Gunner,
Antelope is a pretty easy do-it-yourself, if you don't care about a "book" animal. The tags aren't that hard to draw, most Fish and Game departments will help direct you to the right area to apply, (considering access), and the hunting is pretty easy.
Idaho is a lousy Antelope state, in my opinion, but I think you can draw a tag for a buck with about 50% chance of drawing each year. Success in killing should be about 60% per day, so in two days, you should have one whacked. I think if you applied for MT, WY, CO, and maybe Idaho, you would have your tag, in one year. No need to pay outfitter fees.
Camping during speedgoat season is pretty friendly, since it is Septemeber and early October. You can sleep in the back of a car, eat at diners, and not even have a rough trip.
I am not sure exactly what you were looking for on a 'lope hunt, I think Feclnogn was posting information on New Mexico with $2500- 4,000 guided hunts on ranches. If you want a Public Lands hunt, and you just want a "representative" animal, then DIY is a fun way to do it. Just a little research required, but that will be half the fun, and then come out West, and spend a few days.
I've killed them in two states (Idaho and Wyoming), and I just kind of think they help pass the time after Alaska is done, and before Idaho Mulie/Elk starts firing up.
Good luck.
