Tascam has just come out with a 4-track solid state audio recorder targeted at DSLR shooters called the DR-60D for $349. Two 1/4"-XLR Locking Combo MIC/LINE Inputs, 3.5mm Stereo MIC Input, Camera In, Camera Out, Line Out and Headphone Out. Both 1/4"-XLR Combo Inputs supply +48V Phantom Power and the 3.5mm Input supplies Plug-In Power for microphones requiring a bias voltage. I like the compact form factor, simple functionality and price. There's always that small project, or run-and-gun situation where you don't want to hire a sound mixer but need you better audio than you can record in-camera.
