embryos are hard work for the seller. I havent seen any embryos worth more than $250-300 and can about guarantee i never will.
they will cost you quite a bit more than most people think to get them on the ground. you will probably lose 50% of them on implant, you will not get a commercial calf out of the recip, the vet bill isnt cheap, etc.
It's the off season for buying embryos, and while it's a powerful pedigree, Bullet is unproven, so I think you could get them for $250 to $300 each. I think it's $80 to have them shipped to you. CIDRs, drugs and vet to implant should be about $100 - $150 each. If all goes well you should get 2 calves from the three embryos, maybe 1, maybe 3. About $1300 for what could be 2 very good calves. If it fits your program, go for it.
