PM foot, he's one of the Sabotage chaps and a vanguard tech. They're at Bricket wood this Saturday, I'm sure he wouldn't mind letting you cop a feel...
I drove my buddy Dan360 down to MK to pick up his creed from Dave, he let me have a wee dry fire of his team Demon and I couldn't get over how quiet it was. Add a hopper and paint and it would have been pretty much silent.
They aren't overly huge as a marker either, I think the Etha you have might be considerably smaller, but there are a lot more goodies to cram into the Demon's frame and body
