From what I see in the MEC vid, they are using a loose fit slot for the shell holder, that is why they have the spring wire retainer there, so you don't pull the shellholder out of the press, when removing brass from the press. Not sure if it floats in a 360deg area in there or not. The Forster does allow that between the jaws and the die holder. One thing to check on the MEC press, is whether or not it has to use captive MEC shellholders. Didn't mention that in the vid, they do appear to be normal, but, I'd make sure first. If you have to buy shellholders, savings are likely gone. And when you look at the linkage setup, there is the other area where the difference is, in the price from the Forster. It may make a difference, if you need to form cases or want to use it to swage bullets. Otherwise it is a perfectly functional press, but just not likely to have the leverage you get on a Coax.
