Sorry, my digital camera was borrowed by my brother, as soon as I get it back, I'll have pics for you guys.
Regarding activity, he's more nocturnal. I have seen him move during the day a few times, but mostly at night is when he does his business. However, when he moves, it's very entertaining. He walks around like he's doing karate, waving his 'pom poms'. He doesn't get really big though, probably about an inch.
I'm not sure what he costs though. My LFS owner owed me a favor so I got him in a trade. I really don't see these guys available online too often either.
