honestly the gym equipment u listed from the 90,s is the best ever imo, HAMMER STRENGTH is a must,no doubt,ICARIAN is a must also as well as FLEX, any respectable gym has them, u gotta go with your gut instinct on it. just think about the peices u enjoyed most n the peices u felt the movement from start to finish,ive always noticed the more hardcore folks go with the icarian n flex and hammer,when they r not at the power rack or on the flat bench,squat racks ect ;)as long as u have a fair amount of dumbells, flat benches,incline,decline,squat racks,leg press,seated delt ect,u know the basic shit,u will b fine,throw in acouple treadmills n recumbnent bikes n your on your way.then little by little add afew peices here n ther, u been in the game awhile n i think u will b highly successful doing it n more importantly u r doing something u love
