Here's a wonderful video of the group 'Taraf de Haidouks' using two Cymbalums.
Charming it may be, but I warn you, watch out for the part near the end, around 5.30 mins, where they start playing really fast & the Cimbalom player & the Cymbalum players duet! At first the Cymbalum, which is hanging round the players neck, is turned upside down while he uses it like a drum, beating out the rythm with his hammers, then he spins it over & starts dueting or dueling with the Cimbalom player ... spectacular! I love it!
Oh & just you try keeping your feet still during this video!:
