Any recommendations on a protable audio recorder to go alone with a DSLR camera?

I would vouch for the Zoom, it's a great piece of audio equipment for the price. Batteries can go quick, especially if you are running phantom power to a mic, so beware of that, also you will want to make sure you bring the power adapter if you have wall outlets available, again, just in case the batteries go dry on you. The sound quality is great, and it's affordable.

What Tucker says is right about the record rate, although you can correct the rate issue in Post if needs be, not fun, but doable.

Chris. I use a Beachtek, which is similar to the Juicedlink and so far, so good. The sound quality ont he Zoom is obviously better, but no complaints from clients yet. It cancels out the AGC.

Thanks Tucker. I assumed that separate audio was really the only way to get the best recording. But for some cases the JuicedLink DT454 seems acceptable.
