Assuming good trophy animals...
Axis - $2,500
Blackbuck - $2,000
Aoudad - $2,750
Fallow - $2,750
Japanese Sika - $1,750
Oryx - $3,000
Pure Mouflon - $2,500
Corsican/Black Hawaiian/TX Dall - $1,500
Sika and Blackbuck are $1,500 if you shop around and wait for a deal. Axis is $2,000 to $2,500 at a lot of places. I'm seeing Oryx for $2,500, which is what I'm looking for right now and think I can find a better price if I hold out for a special. Niglai are also in the $2,000 range, which is another one I'm watching. Pere David for under $3,000 with the best price at $2,500 so far. I should have jumped on that one, but was too slow.
