I have three new kegs (all came with my Beer Meister). One is made by AEB in Italy and the other two are made by American Cylinders in India. I just got started kegging, but so far, the AEB keg was great. I was just getting one of the American Cylinders ones ready for a batch this weekend and while they are heavier and therefore feel more solid, I needed a rubber mallet to get the disconnects to lock in place. Once I got them on, repeating the process became easier (I can push down hard, rotate them a little and push down on the locking ring of the disconnect). I'm hoping that these aren't going to be a problem...
