Spinetti's is still in business (but has recently moved), Did you give them a call? https://spinettisgaming.com/

If you are in LV you may consider going to Bonanza Gifts (https://maps.app.goo.gl/pws6f93128tdjieG7) to see if they have something like that.

You may also consider going to the CCA Show ( https://www.ccgtcc.com/events/convention/index.aspx ) and asking around there.
