I haven't heard of them, but there is a breeder in FL I know of who is super reputable and ships. Her name is Peggy Brewer and her company name is Critter Love, I'd link the website for her, but I'm on my tablet and it's rather challenging for me to do such things. Also, I've heard of The Pet Glider (TPG), I'm not sure where they're located, but I thought they were in TX, but maybe not. It wouldn't hurt to google these breeders and check out their websites, I've heard many good things about their gliders. I believe there are at least one or two more I've heard of, but think they're farther away and not sure if they're shipping.
