The Exmark Turf Tracers are good machines but I'm not sure the deck would be the greatest where you are...wet a lot right? I hear good things about the new Scags decks not clumping in wet condtions.
You have Exmark dealers nearby and one of them is also a Husqvarna dealer too...Steel Street Power Equipment in Lakewood. You also have Scag dealers in Edgewood and Sumner. You've got John Deere dealers in Tacoma and Olympia. Not sure how far any of those places are to you time wise and I don't know how current it is or exactly what they all sell and service. You might also consider Ferris and Snapper Pro.
