I have three Saharans, an adult male WC and two CB babies. Gizmo, our adult male, did amazingly well with acclimating when we brought him home. I attribute this to the fact that we had everything completely set up properly before bringing him home including enclosure, lights, temps, foods, etc. Also, the small locally-owned store we got him from does a really good job of taking care of their reptiles compared to any other store I've seen. He ate well and was curious and not afraid from the first day we had him. He did have pinworms that he was treated for, and though he was a bit skinny, he had gained a good amount of weight and is a wonderful guy. The one thing he HATES is when we try to touch him. He will eat out of our hands daily and doesn't shy away, but we just can't touch him except for taking him out to clean the enclosure or for vet visits.
Our babies are about 4 months old, and though they're both CB, one is very friendly, outgoing, loves to eat out of our hands and doesn't mind being held (only rarely and for only a minute or two). The other baby is still pretty skittish and runs and hides a lot, though she is eating well and basking and doing all the things that baby Uros do, she just doesn't like an audience.
So... they can be acclimated, and after talking with others who have Saharans, I think we really lucked out with our big WC male in that he had no adjustment issues. As for the babies, goes to show that even though they both came from the same situation, they have very different personalities.
