I dont really rate Pinballs as A or B list machines so long as it something you want. People still go to my $500 Gorgar than my $2500 Creature
I would rate Gorgar as an A list machine though, irrespective of purchase price, it has that aura and reputation that makes it a well known and desirable machine. Maybe instead of A list and B list I could say well known and lesser known machine/s.
