EB's body (at least for the 1/4 Begins Batman) is indeed cheaply made. I think it was 2 years ago when I posted on the EB Batman thread that mine broke by the shoulders as I was very carefully raising the arms laterally while cleaning the suit. I had to remove the suit to see and repair the damage -- and that's how I found out that the shoulders and chest were connected by a hinge made up of thin, brittle plastic and a tiny screw that might suffice for 1/6, not 1/4 scale.
That suit material may not be for everybody, but it's surely tough! I did the "liposuction method" to make the belt fit and lose that gut, and it can withstand a good deal of stretch.
The belt, grapple gun, batarangs, and bombs from EB look very cheap as well compared to those that came with QS HT TDKR suit.
