Best Budget Digital Audio Recorder?

[TomCooper]

Hello all,
I've started shooting videos of cars using my Lumix G10. The video quality is great however I would like better quality audio. There is no port for an external mic and I therefore am after a cheap'ish' digital audio recorder to record the sound and then I'll sync the sound with the video on my computer.
Are there any good budget digital audio recorder that people can recommend?

Thanks in advance,
Tom

Haven't used one, but the Zoom H1 seems well recommended.
