Had a quick eBay look and it seems like "Winmau" dartboards can be had here for about £80 or $120, so that's not bad.
It seems that even the nice dartboards have metal grids to separate the scoring areas. What is the rule about "bounce-outs" when a dart hits the grid and just drops to the floor? Do you get to throw again or is it just hard luck?
We live in times when smart people are silenced so that stupid people won't be offended ...
