ok... Lowrance Structure Scan or Hbird Down Imaging???

Tap says hhe rarely uses DI on is Hbird. I have done some research and apparently the Lowrance is WAAYY more advanced than Hbird. I am not prejudice one way or another. But since I cant afford SI I may as well get a big screen DI unit. But I want the best one for the best price (who doesnt right?)
