I used two analog light meters (sekonic and gossen) but I found that they weren't very accurate. I can safely say that this isn't the case for all analog meters, but I wanted to buy a new meter that I could trust so I bought a Sekonic ... something... can't remember the numbers, but it was digital and about $160; it was definetely worth it, I can't tell you how many times I've dropped it, gone through rain, abuse, etc, and it's still working great. What's nice about it is that the lens (or whatever you call it... light sensitive thingie...) is fixed, so it's much more stable than the meters with rotating heads. This also makes it worse for taking reflected light readings (the Gossen Luna meter is much better for that) but almost every reading I do is an incident reading, so it works super for me.

But if price is an issue, like everyone says, you can pick up a meter for less than $20 on ebay; just make sure that they're accurate!
