Well, here in Sweden, EM's go for at most 400 USD (regardless of condition, they are simply not as popular, and only a few/handful hobbyists like myself would put in work to save/restore one) and "unpopular" 70's/80's pins like you posted (usually) dont go over the 800-1000 USD level, while "popular" late 80's and 90's pins go for astronomical numbers, due to smaller market and fewer games.
For example, going by own games and the prices ive seen them go for/had them priced for here it would look like this.
Williams Jungle Lord = 1075 USD nice condition/fully working.
Gottlieb Arena = 1433 USD nice condition/fully working
Williams Grand Lizard =1194 USD nice condition/fully working
Sonic Segasa Gamatron =955 USD nice condition/fully working
Premier Stargate = 1792 USD nice condition/fully working
Now my games are not exactly in nice condition in the cabinet area (usual wear on the artwork etc) and Stargate have a worn playfield, so some of the pricing would probably have to be adjusted lower if i sell.
