This is a difficult can of worms to discuss.
Import is to Captive Bred/Born (CBB) as Kmart is to Dillards.
Well, it comes down to quality. While some imports will readily feed, most will not. You can easily spend countless hours, days, and months trying to get them to feed. I have dealt with both and I can tell you from experience, I'd much rather deal with healthy CBB than imports. In the last 10 or so years, I have purchased many imports but have only kept 1. She took nearly 8 months to START feeding and was not a consistent eater for about 18 months.
Many people think imported adults are a quick shortcut to breeding success. I find most imports won't let a male near them - at least not in the first year.
Some people also believe buying imports fuels the "trade" industry and hurts everyone in the long run - I won't tell you which side I'm on.
Many imports die in their first year in captivity. Vet bills can be high. Some feel they give Flagyl and Fenbendazole and the animal will be fine, while in reality, these do not cover everything.
There are some who specialize in imports and for them, it works. For most, it does not.
Food for though.
