I had to eliminate 'T nut' and 'belt' from my eBay South Bend searches as half of the returns were T nuts and belts which I have no current need for.
As for the Aloris style post and locking lever, my KDK's are nicely off to the side. I have the 0 size on the SB 9" and the 100 size on the SB 13". I always liked the clean top of the KDK style. Although the KDK's can be found all over the USA, they are certainly more populous on the West Coast as they started in the LA area...
