yeah Audacity is freeware, and all you really need is a direct input box, which will convert your hi-z connection to lo-z, then you can plug it into your computer, or you can get a fairly cheap fairly decent audio interface, usb or firewire, and record from that


if you don't want to bother with the computer, get a multi-track recorder

if you want something small, there's the new TASCAM DP-004 Pocketstudio for $199 that will record guitar and vocals

there's also the Zoom H4 Handy Recorder, about $270, a portable recorder with a lot of features

or Fostex MR8 MKII 8-Track Digital Recorder, about $250
