Ebay, play it again sports stores, other hockey players selling their gear for low cost equipment that you're 100% sure you want.
Local "mom and pop" hockey store - prices may be a bit higher, but you'll help them stay in business. Sometimes they too will have some nice sales [I picked up a $210 CCM Crazy Light Hockey stick for $105 a few months ago]. Some shops also sell used gear [consignment].
Hockey Monkey [forward gear] or Goalie Monkey [Goalie gear] - excellent prices and an awesome return policy.
