microcontroller - Should I buy a Netduino or Arduino?

I am looking at buying a NetDuino for some fun home hobby projects.

Have any of you used it and how was your experience?

Should i look at the Arduino or FreeDuino range instead(or something totally different)?

I decided to stick to the NetDuino due to my C# knowledge, but that is not a requirement.

Thanks

PS. I am not sure if this belongs to the community wiki or not (guidance appreciated).
