I have long admired Sound Devices gear, but found it a bit annoying that they sell separate component mixers and recorders, which is probably ideal for a dedicated audio pro, but a bit unwieldy for me.
Tascam has just launched a new 8 channel location recorder for the production industry which looks very interesting. I'd love to have more than 2 channels of audio, though this is a $5,000 field recorder:
