Boris recommends this (and I can borrow his expensive microphones initially). It sounds good, compact and good fidelity. If anybody has used this for Podcast recording on a Mac, let me know what you think.

MobilePre USB is the preamp with a built-in audio interface that’s designed for laptop recording such as field recording and sampling expeditions. In fact, it’s one of the only completely bus-powered preamps available. (Of course, you can use it on the desktop as well.) A total of three kinds of audio inputs and outputs provide maximum flexibility for any application—including two on-board microphone/instrument preamps and high-impedance instrument inputs ideal for connecting guitars and basses. And unlike many competitors, zero-latency direct monitoring provides you with a streamlined professional recording experience.
