The cheapest way to go is Axanthic Pinstripe x Pied it will also be the longest route 6 to 9 years if lucky.
First step you will produce Pin DH Axanthic Pied and DH Axanthic Pied
Second step you raise 1.0 Pin Axanthic Pied and at least 0.2 DH Axanthic Pied
Third step you pair them together.
It's gonna be a long shot, a lot of time, a lot of babies (DH without a reputation will be close to impossible to sell) and a lot of extra expenses so what you need to gauge is if all that is worth the time and money or if you start saving now and be able to buy one in let's say 3 to 6 years.
