Depends on your budget and patience.

Let's say you spend $150 on a pair of het pieds, you will have to include housing for 2 snakes + food + electricity + incubator + hatchling rack and wait anywhere between 2 to 3 years before your first pairings, if your odds are good you might produce a pied the first time around if not could be another year or two after that.

Or you can buy a pied which are anywhere between $350 to $500 and have the snake you want now not in several years.

The choice is yours, I have done it from scratch buying a pair of het pied and I can tell you there is nothing like making your own, the difference however when I het pieds back then were $1200 a pair and Pieds were $7500/ $10000 , hence why I bought hets at the time if I was to do it today I would obviously get visuals from the start.
