The machine that revolutionized the home fitness industry, Soloflex, is still around and selling their wares. I bought a used one many years ago for around $100 - a fantastic deal! I bought a new set of bands from Soloflex as the used ones had some wear.
The unit itself is built of very heavy duty steel, almost indestructible. And you get a fantastic spotter-free workout with minimal room required. And of course, it's made here in the US.
And check out the new Soloflex Buddy app for the Soloflex too!
