I have the Saitek Gamer's k/b, which is an Eclipse, (only silver in finish) with an added game pad, that attaches via 1394 plug to k/b, other words, same 104 key, board.
No issues what so ever with multiple keys pressed, only once, but it was due to "hot keys" on my ctrl key, pushed 5x's inna row.
I've had mine 2+ mos. and the "D" key is starting to show paint wear, but I play a lot. I see the eclipse, has silver keys, with laser cut letters, (that allow the backlight to show through) where mine are black, with white paint, so that might not be an issue for you.
Guess that shipped cost is ok, I only paid $42 for mine locally, with the gamepad included. You'll like it, nice feel, and I <3 the backlit display.
