GPS Chartplotter CHIPS suggestions

[Flaming Antler Outdoors]

Got rid of my Lowrance HDS 5 and bought a used HDS 9.  I think my 5 had navionics but it was put on by the factory or dealer.  I am looking for a chip now for the 9" and was thinking the Navionics platinum plus (Puget Sound) marine chip.  I see Garmin also makes them.  Any suggestions or input?  I think they use to be 99.00 but looks like they are more around 175.00 or so now. I fish puget sound, Sekiu, Neah, and Lapush so the Puget Sound card covers that.  Thanks
