Q. I need (OK, I want) a helmet camera. I like the GoPros but I don’t know which model to get for filming while skiing. What would you recommend?

A. I love the GoPro cameras, too! Which model you should buy depends on what you “need” from a small waterproof point-of-view video camera like this. If price is a concern, look online for a used or new entry-level GoPro SD Hero 170 (retailed for $100), which GoPro has stopped making. This one came with a helmet/head strap plus a couple of stick-on mounts, shoots standard-definition video and 5-megapixel photos, and is powered by two AAA batteries. It’s everything you need to get started shooting helmet-cam movies.
If your heart is set on capturing high-definition video, spend $180 and go with the GoPro HD Hero 960. HD Hero comes with a rechargeable battery, which will save you money in the long run. If money is no object, go with the top-of-the-line GoPro HD Helmet Hero ($300), which comes with more mounting options and is compatible with cool new accessories including the LCD BacPac, a little mountable video screen that lets you see what you’re filming in real time.
