More recently I purchased a Tiltable Stage from E-bay(eBay item number:295576941874). The base of the stage is sized perfectly for my Leica stand, measuring 120 mm in diameter.
I did not pay the asking price, nor should you. It required a few changes to be fully useful in my opinion.
As is, the stage will not hold position on the base. There is not enough friction. I corrected that by placing a small film of silicone around the rim of the base.
The surface of the stage is not suitable for using insect pins etc. I added a cork surface, sufficiently thick to allow pins. The cork surface is ..wait for it.. simply a coaster. You can combine more than one if you need a greater pinning depth.
These 2 small changes assisted a lot.
