Recording around a table

I'm shooting DV and need to record between 3 and 4 people seated around a table talking. It's an interview situation with several people questioning one person. I have two questions:

1: What is the best mic - or mics - to do this with? (They can appear in the shot so sitting on the table is perfectly fine.)

2: Is there a reasonably priced field mixer out there I can use to mix these down to two channels?

Thanks a ton!
