I'm not familiar with that particular machine, but I can tell you an automated grommet machine is freaking awesome.
The one I used was an ancient model, and one of the feed belts was broken (you had to turn the feed drum to have the grommets drop into place), but it still beat putting grommets in by hand any day. You could turn the drum a couple of times and have something like 20 tops lined up and waiting. All you had to do was put the washer on the bottom of the die, put your material over it, and step on a foot pedal. It sounds weird, but it was so much easier than having to punch holes and set grommets by hand- or even using a manual press.
We also had it mounted on a pedestal with wheels so we could move the machine easily, which meant we weren't limited as to where in the shop we could use it.
