I looked there as well. They do not have any straight shank arbors with a 1/2"-20 thread (w/collar) either. Closest they had was an R-8 arbor with .0008" accuracy - four times more run out than most of their other arbors listed (that won't work for me) that show .0002" accuracy. But I don't want an R-8 arbor anyway.
I bought a couple of straight shank arbors from All Industrial. When I get time, I'll have to get out a DTI and check them. I don't have high hopes though.
