I've read that the angel island chuckwallas (cbs are typically available in late summer) are comparable in tameness to beardeds. But, they also get pretty large and will need a big tank (hopefully someone who has more experience with them will chime in).
I've got a pair common chucks. If you want a pet, cb is definately the way to go. Wild caught chucks tend to be pretty skittish and can be difficult to acclimate. They are also often in poor condition by the time they are received. My wc female still runs everytime I reach in the cage despite the fact I've had her for over a year now. My cb male on the other hand, doesn't mind coming out for the occaisional visit and will readily take tasty tidbits from my fingers.
Chucks like lots of rocks and tight hiding places, just make sure the rocks won't shift. I've got my pair in a 100 gallon tank with a 120 degree hotspot on one side, a cool side in the mid 70's to low 80's and full spectrum / UV lighting. Chucks are primarily vegetarians, but my male likes the occaisional mealworm as a treat, my female, however, won't touch insects. Brightly colored asters / daisies are real favorites, especially dandelions. A wide variety of herbs, ornamentals and weeds are relished (dandelions, pansies, mint nasturtiums, plantain, alfalfa, hibiscus, etc). Since I live in central CA, I find using these cheaper and more convenient than using store bought greens.
Chuck eggs tend to start hatching in mid summer to early fall, this is the best time to check the classifieds. It's worth it to wait for a cb. They are much more forgiving than the cheaper and more readily available wild caught individuals. With a cb you're much less likely to encounter the heart break and difficulties that a lot of the people who buy wild caught seem to face.
