If your intention are two breed yes $1000 and up animals are something you will have to invest in if you want to remain competitive produce superior animals, make a return and add to an already flooded market when it comes to common morphs or in the case of carpets Mutts.
If you want to make a return whether it's just to break even and have animals paying for themselves, have a little additional income or making a living, you will have to upgrade your collection every year and invest money, if you don't you will lose money each year, some people understand that and some don't (aka collection sale after 5 to 10 years)
That's for the business part regardless of the species.
Now for the pet part some people spend 1K+ for a dog or a cat, some spend 1K+ for a snake if that is something you truly like why not so long you can afford it.
Now as far as carpet I am picky I like lineage and getting the best animals. I like the fact that I have some pure Albino Darwins and purity is often in question with many sellers that either don't know or do not want to tell, with Nick Mutton you won't have that issue.
