I have three Saharans, an adult male WC who is very tolerant of people being in the room with him, but hates to be touched in any way. We were very lucky in that he really didn't have an adjustment problem and took to his new enclosure and ate well from the first day we had him. But.... if I had it to do again, I'd definitely get a CB.
In the last two months, we've gotten two CB Saharan babies, one a female and the other unknown. They were together at the breeder's, and we've kept them together without any problems thus far. One went on a hunger strike and got dehydrated, needing a trip to the vet for fluids, but has bounced back incredibly well and the two get along great. They do have very different personalities, even at their young age. One is very outgoing, wants to see everything going on, eats out of my hands daily, etc, and the other one is a lot more skittish, runs and hides at a lot of things, and keeps its distance.
For a pair, you need to make sure there are multiple basking/hiding/feeding areas so that one can't intimidate the other one. It might be so subtle that you don't notice it, but giving plenty of space lessens the chance that one will dominate the other. I've heard from several people that the Saharans are some of the easiest to keep in pairs.
If you decide to get Uros, do your research first, look up care sheets, and make sure you have everything properly set up BEFORE getting them so that they have as much of a stress-free transition as possible.
Keep us posted on what you decide to do...
