Digital Camcorders Reviews

I intend to snowboarding this year and I did not have a camcorder. I was so many types of camcorders, and I found that some high-definition, and they are not very expensive. Therefore I would like to know how to work this business from SD cards. I could not find any info in the technical details of the camcorder, how it records video. The SD card technical details do not say anything. So if someone can help just let me know about this, I will thank you. Even if you give me some advice it would be a good HD camcorder, which will not take more than $ 500. Or what do you recommend to buy with the fact that the device operates at low temperature. I am satisfied with the quality of care, but if there is not much difference between the quality of a regular camcorder, digital images and high definition of a person, so let me know. Thank you very much! And excuse my English!
