Portability isn't a huge issue. I don't need top of the line. I'd like to be able to record bass, guitar, and vocals, preferably without an amp. I'd like it to be firewire, and to use the firewire interface for power. It doesn't need to be portable. I've dug through a lot of threads and searches here and am overwhelmed by the number of choices out there. The sticky pre-amp thread looks great but I'm not sure if I need one of those or just a firewire interface. Is there one that can do both? My budget is 20 dollars to 500 dollars, although I'd obviously rather not spend more than I need to. Thanks in advance.
