tonycon, thanks for the the reply!
the thing is, I am one of those ( maybe rare!) paintballers that sees his marker as a object to play with! not to protect and keep in perfect order to keep the resale as high as possible. I just want to go out and play and not worry about possible damage en bends.. just use it what its made for, shooting.
So in that case the Etha would be the better of the two, less scratching on composite compared to aluminum. I don't care if a marker is used or not, I care with how the owner treated it
. Nevertheless 12 months warranty on the Etha would be great. And last but not least, I love a LCD on my marker but i might be able to get on with a LED, seems so easy.
Still very interested in opinions of players who have used both.
