I have a "Gladiators" and we really like it. It was my first DMD pin....when I went looking for a game of that era I had asked around for recommendations for games that were afforadable, fun, dependable and servicable. The System 3 games always came up. Mine was missing the shaker motor, but I was able to piece one together with the schematic, parts from PBR and a few items from Radio Shack.
And if you need parts, they are prety much all just a call or click away from PBR.
Maybe in the future I will add a "Stargate" and a "Barbwire". Maybe even a "Waterworld"...I seem to be one of the few who actually enjoyed that movie!!
I think they are a good deal for the price.
