Reply to Recording on the fly: Digitial Recorders?

Just wondering what people have found for a solution for recording sets live. Right now it's one of my bigger issues and I just don't end up recording any of my live sets.

I mix externally with an SL1 box, so I don't have the ability to just record in the SSL software. Usually when I'm at home I just run a cable from the mixer's record out to the input on my computer, and have Ableton going and recording at the same time. Honestly I want to get an SL4 in the future, but it's not something I'm looking at right away.

Running a lot of software programs is not something I really want to push live at a gig though. I'd much rather just have a small portable digital recorder to hook up to the record out on the mixer, and not have it eating up computer resources at all. It's just something I'm probably a bit overly worried about, but the last thing I want is latency when playing live, or any random spikes.

Does anyone have any suggestions for portable digital recorders that they have used?

I've been looking around, but it seems almost all portable recorders have the live / drum / guitar musician in mind, and not just a simple recording tool. I mean hell, I could use a walkman, but figure digital would be the way to go.

Any advice would be great
