I actually like that the Poker is PCB mounted, it makes pressing the keys a little softer than on a metal plate, not sure how other people feel about this though. I've never really been all that worried about build quality, it's not like I ever had a keyboard fail out of the blue from normal usage (thought that has happened to me with two mice).
The weight of the keyboard has never been something that really impresses me either, is there a cut off point where weight starts to be considered bad or is the two ton keyboard going to be the best even if you can't put it on a table without the table collapsing?
