Depends on the $ you want to spend. If you can afford the touch screen model then by all means purchase one. One good piece of advice about buying computers (which a fish finder is) always buy the newest technology you can afford. I just recently purchased the Garmin 94SV because for what I was after and could afford it was most definitely the best value. My first was a Lowrance Elite 5 DSI convinced I needed to by a Lowrance after owning one I am convinced by what U want that is in your $ range
