I agree with some of the lads, saluki crosses can be a bit of a pain, saying that, all dogs can be b*****ds at times. Whichever cross you decide to get, make sure the parents are good at the job that you want the pup for so in your case lamping and ferreting. A pup with good feet is important too as there is nothing more annoying than having a laid up dog all the time.
Good luck with whatever you decide to do though fella
