Can anyone recommend an A/C Nano charger?

[Malpaso]

I recently purchased my first ipod, a 3rd generation Nano, and since I'll be traveling soon I thought about getting an A/C charger. There are so many knockoffs out there, and many pro and con reviews, I was wondering if anyone here could recommend a dependable and inexpensive one, and where to get it (hopefully from a CPF vendor).
