depends when yuo go. mondya and tuesday evenings seem to be a bit busy but there isnt much waiting around for machines. fitlinx is a computerised system that helps you keep track of your machien usage, lets you know when you are reaching/exceedign yuor targets and can tell you when you are going to slow on a machine. its good to have but not worth an extra couple of hundred a year. actually, i cant comment on total fitness and dont know if they have it or not but i can live without it.
