E1405 Keyboards and Keys

I've had several keys pop off since I got the E1405. First one I was able to get back on somehow, the second looks terminal. Guess I need a replacement keyboard since the "6" key now looks like it's waiting for the right moment to jump?

I've not been a real fan of the keys on this board from day 1 because the edges of the keys tend to "grab" your finger-tips if you get too close to a neighboring key (the "9" key will catch my finger when I hit the "O" key, for example).

If I have to buy a new board is there a replacement board that fits the E1405 that has a different design for the keys and/or how they're attached to the board itself?

I don't care if it's from Dell or a third party, I'd just rather have a board with keys that don't fly off just because you have kids or the dog tried to type, ya know? Anybody know where to get a compatible but stronger board? (Weaker kids is not an option and the dog eats better than I do...)
