the total gym is a funny thing.
you use your bodys weight as resistance so you do max out very fast. but you can build lean muscle very fast and i havent found any better other than hanging up side down and doing sit up and back extension for training your core. there is also no better warm up, streching and cooldown streching machine out there for this money. if you need work on your groin, hip flexors abductors minor muscle groups in your back shoulders chest neck and legs, this is the way to go.
if you have sportsmart( i think there are under a different name now) they might have some to try.
my neighbor has a boflex and he paid about $1500 for it
They say the END is near, but I'm Tired of waiting.
