Look for those that have separate cups and stems and make sure you get the ones that separate at the top of the stem not at the base. No cutting needed and very cheap.
I don't think I've ever seen any that have the stem attached to the base, but I'll be looking!
One thing that works surprisingly well for fairly large saucers is a party glass, the kind with LED's in the base; you turn the glass over, put the saucer on top, and the light show can be impressive. The hard part is finding one with continuous 'on' lights.
Most you press the button, and it runs for seconds.
Don't know how large your saucer is, mind.
