Heatwave I have seen 200-300 dollar range. Ali, last I heard was around 200, Meyer 734 if you can find it will run the most. Last guy I called on some 2 years ago wanted 500 a straw.
I have heard $700 on Meyer 734. But you could do invitro and flush several cows with one straw. Why not use his son, Macho. The calves are fancy and good haired out of Angus cows and the semen is only $30. Launter has Heatwave for $250 last I heard.
