His are the plastic L shape acrylic ones. They work just fine for displaying the plaques.
As far as the black ones found on the MR LE and EE hilts... Rebel Scum had them a while back ago but are not producing them anymore. People have been looking for these for quite some time.
Getting the ones from him work great, anyways... so I agree... you can go through him (I've also had some stuff from him in the past, if you haven't noticed... plaques, plaque stands, and lightsaber stands :) )
