I have used the following two strips with the M100 SysBus socket for quite a few projects - not sure it is the same format as the NEC socket. The strips are very low profile which means the modules easily clear the cover, even with tall components on the top side. But they are expensive which is OK for one or two modules but perhaps not for mass production.
