Speech Database Collection: Preferred equipment/soundcards?


We are trying to collect a speech database for our application.

In our experience laptop soundcards are notoriously bad with introducing strange noises into recordings, 60 Hz or otherwise. And I read on auditory list sometime back that USB external soundcards are no good either. So, we are planning to use  a Dell Desktop and do recordings in a sound booth.

However, I wanted to find out if anyone has any experience with the kind of equipment that works best for it? Should we be careful about what kind of a soundcard do we use? Does anyone know which soundcards work best? Is there anything else that we should be careful about?

Any kind of help will be greatly appreciated!
