If you want a fair priced wild sable look into Mozambique, the prices have gone up but are still somewhat affordable.
Ive posted this picture before but thi is what kudu and gemsbok think of fences in the Northwest province of South Africa. This was on a sheep and goat ranch.
Cattle fence, no issue to jump over for most of game. Gemsbuck is usually lazy, he will be running alongside, and when decide to cross he will try to pass through rather then jump over.
Animals that jump over fences: Kudu, Impala, Eland and Waterbuck
Animals that crawl underneath or through fences: Ungulates like Warthog, Bush pig, Duiker, Steenbok, Klipspringer, Gemsbok, Springbok, Sable Antelope, Red Hartebeest and Tsessebe, and the predators such as Jackals, Caracal, Cheetah, Leopard and Lion
Animals that break fences: Elephant, Buffalo, Rhino’s, Giraffe’s, Waterbuck, Eland, Blue Wildebeest and Sable antelope bulls
Animals that usually do not jump over fences: Springbok, Blesbok, Steenbok, Duiker and Oribi
South Africa has regulation about game fences, and based on species of game kept within fence, there is different technical specs required.

similar behaviour traits – 1,8 m high with six wire strands, which must be of plain
wire. For ostrich chickens, wire netting is used.
