You do not really need a metric drill set. Look at the referred add from Harbor Freight from CA. This 115 piece is usually on sale for $39.99. I just received their latest catalog and it is priced at $39.99. This is every size from #60 to 1/2". All you need with these is a drill chart. mine is by Starrett.
