I found these videos on you tube... They are of the older style Ironmaster. Since Ironmaster has no real operation manual or posters for the old style, I was able to pick up a few hints/tips for use mine, in between marketing BS . If the person who posted them is a member here, many thanks!
A few more IM videos
As far as a review I will say that the machine is far from perfect. I'm sure there are some who would despise the machine as its not commercial quality, and its a fixed machine like a smith. Its also not a substitute for a power rack. Since I'm on a very tight budget though... It is the best, $70 I spent on my gym so far! I feel the videos do have a big fault by not mentioning the possible joint problems you can cause yourself if you use a smith type machine without proper care/form. With care though, I have found the exercises feel a lot better than the Powertec Lever gym I had before. The slides are smooth even when uneven weight is used. The Ironmaster frame makes a great place to hang simple and cheap nylon webbing for spotting safety when using dumbbells, etc at home.
Finding them used and cheap isn't a problem on Craigslist. I missed out on one months before I got mine that was only $60! Most of the time they are listed for a few hundred. Of course you find them listed for $1000 too, because someone thinks they are the same as the current IM2000 (close but not quite). A lot of the older models were made in the USA, not China. I have a smaller version called an Ironmaster II. It fits very well in a tiny bedroom and takes standard weights. Standard 1" weights do have some advantages for the person on a budget, as in they are given away quite often! They are not that bad to use outside of the Ironmaster either, providing you spend a little money on quality Ivanko or Hampton standard bars (under $50 for the Hampton, rated up to 330 lbs load).
Here are a few listed on CL today.
