Cheap 1-pre interface that doesn't completly suck?

[Wolfeman]

I need a cheap interface to hook up to my Mac Book Pro to use for reamping
signals to my amp builds in my basement while I'm working on them. What do
you guys recommend in the cheap realm?

Here is what I need at minimum-

1 mic pre
Outputs for monitors
Output for reamp signal
USB or Firewire, doesn't matter since it's only for one track at a time.

I know a lot about higher end interface, but not so much about the cheapos.

Never mind, got a Focusrite Sapphire 4 in 10 out on the Ebay for $130.

Hope it works in Snow Leopard
