The technology is really getting quite cost effective. Here is a 24b 192kHz two-preamp USB audio interface for $60 USD. Amazing. This is perfect for a quick, on-the-go interface for mobile recording -- especially for electric guitars. Just plug in directly (no mic) and use a laptop as a DAW and run Reaper with some free VST plugins and you are ready to go!
