Bill,
I haven't tried that model. Assuming that the catch has the same realistic feel, folding for storage/transport would be a nice feature. I give local stroke clinics from time to time and have wanted to take my erg (as it is a fantastic coaching tool), but not having a truck or van, it always stays at home.
If you don't need to travel, then I keep mine on carpet pads behind a coach against a wall and just slide it (over hardwood floors) to the center of the room when needed.
There's a few good threads about ergs on this forum. Here's an image that I posted previously:
Best,
Greg
