I purchased a U. phantasticus from Sarah Dickenson at lunargecko.net a couple of months back. She was patient in describing her standard of care, and answered all of my questions.
Since the weather's been so crappy where I am, she was more than willing to hold him for me, and while we were waiting for more ideal weather, she did a great job at keeping in touch with me. When we had a good-weather window, she got right in touch with me immediately for delivery planning.
Just got the animal today, looks alert, and it was extremely well-packed. Sarah contacted me right away post-delivery to make sure all was well.
Everything went great - highly recommend her!
