Yes, Star San is pretty much the home brew standard, though others will also suggest iodophor. Star San isn't very expensive at all- my LHBS sells an 8oz bottle for $10. All you need is 1oz for a 5 gallon batch of diluted Star San, and as long as the pH stays below 3, it still sanitizes effectively; I just started using it a few weeks ago, but according to others a batch can last for months if properly stored.
