If you go the E-Mu route make sure it's PCI-e or USB, they (Creative) ain't too hot on driver updates either.
I went from a 0404 to a Roland Quad Capture about 6 months ago, I forget it's there, it just works. Clean, quiet pre's with plenty of gain. I run at 64 samples latency at 24bit/48000 Hz all day long without a glitch. USB bus powered so it's truly portable too.
For vox and a guitar it's a perfect solution at around £150 street price. Mac or PC
