Shox is absolutely right. I've had a neogames metal pad I bought from eBay two years ago, and it still works just fine.

Problems I've had:
The LED lights are picky and don't work on certain PS2s.
The plastic on non-arrow panels peel after some wear.
The contol box with the start and select buttons has fragile parts; yet, that's true of any unit with solder points.
The metal dividers can bend if you step on them the wrong way. But, they don't affect the arrows.
The plexi is slightly cracked. That will happen with any pad.

Note that they've upgraded their models since then, so many of those minor issues may be fixed. For example, my cousin got a newer one, and the metal was tinted blue instead of having white plastic sheets. They come between $100-$150. I highly recommend it if you can get past some of the tiny nuisances and you're on a budget.
