($195) Leverage Squat Machine - Made by PowerTec, this machine was in the gym we owned. I liked the machine so much, I kept it after we closed down the gym. Knee is bad and can't use it anymore.
I also have a Champs Bench Press that does incline and decline as well as flat. The bench also has a leg extension and leg curl attachment. It comes with a 45# bar rated at 600#s and clamps for both ends.($135 for bench, bar, and clamps)
Also have two 45# Ivanko OM Plates($90) and 215# of rubberized TKO weights($118 =.55/#)
Total used price is $538 but willing to take $419 if you take everything.
I've included internet pics so you can see the value of these items. They spent a season on the back porch but are still in decent shape.
Prices vary, but I added up the prices I found on the internet for kicks and grins. I'm sure you will find cheaper and more expensive websites; I just did quick searches at reasonable places.
TKO came out to $2/# or more (so $430)
Ivanko came out to $2.33/# (so $200)
Leverage Squat was $652
Similar bench was $195
Bar and clamps were about $130
That total came to $1,577, but this is Americanlisted material, so it's priced at 1/3 the price (or better if you take it all).
