csv

I have a tab-delimited file that has over 200 million lines. What's the fastest way in linux to convert this to a csv file? This file does have multiple lines of header information which I'll need to strip out down the road, but the number of lines of header is known. I have seen suggestions for sed and gawk, but I wonder if there is a "preferred" choice.
