I have a Mobile Pre myself, but quickly found it inadequate for my needs. I bought a Presonus Firepod, which has 8 mike preamps and connects to the computer with firewire. It also allows me to patch in a compressor to the input stream for people who can't sing with even volume. Unfortunately, Gear Acquisition Syndrom reared its ugly head and now I have a dedicated recording computer (custom built), a 2-channel compressor, patch bay, power conditioner, monitors and a growing collection of microphones. I still use the mobile pre with my laptop for small-scale location recording.
