Apple ipod

It repaired the 16GB iPod touch 1G or 2G Apple Store?

Hi, I was thinking of buying the Touch 2G 8GB 16GB that the new key is too small, while 32 GB is too big. However, it does not say if the original key or touch 2nd generation. I do not want the original, only 2g. Thank you.

It the second generation, I think
