I appreciate all the input. My local HD has the Freud Diablo models, of course, and I will look into them. Seems like a good compromise, especially since I am impressed with my thin-kerf Freud Industrial LU91. In any case, I think that the Oldham is officially off my list.

Note that Lowe’s is now selling the grey-finish CMT blades, and they seem to be in the same price class as the Diablo line. How about that CMT model? Is it basically the TK version of the orange-finish versions? Any opinions on performance quality in relation to the Diablo versions?

As for the limitations of a thin-kerf blade in a 12-inch configuration, well, I can see the point. However, knotscott also noted that there is less work for a crosscutting blade to do, so I would imagine that the stresses that normally try to cause a blade to warp somewhat while cutting would be less also. Less blade strength with TK, but also less stress on the blade to begin with. Consequently, maybe there is a strength vs stress tradeoff that ends up with a TK blade doing just fine with crosscutting.
