I always figure on a System 11 you are fairly safe up to about $600 as long as boards & displays are decent. One issue fairly common with Jokerz is sound board issue causing speaker hum. When we needed a soundboard it took us like a year to find one under $200. That soundboard is specific to Jokerz and maybe one or two other games if I remember correctly. It might even be just Jokerz.
As far as gameplay I kind of liked it, my wife was OK with it but my son hated it so we sold ours.
