I have been using an Edirol R-09 for a few weeks now and have ordered some for our MoLeNET project (the Glossy project).

Eidrol have now released a new version the R-09HR.

From Engadget:

Edirol released its high-end R-09 portable recorder back in 2006, and now they’re taking things up a notch with the R-09HR, which can handle 96KHz recordings (up from 48KHz) and supports SDHC up to 8GB instead of the 4GB max of the old model. The recorder also includes a monitor speaker, remote control and playback speed control — a big win for fans of Alvin and the Chipmunks or for those who need to transcribe interviews, two camps which we conveniently find ourselves in.

It will cost £249.
