I have a WSM 18.5 and a Weber gasser for quick meals and a Weber GA for high heat steaks and such. Just the wife and I here now and these really serve our needs.
I've been a Weber fan since my teens, but consider a komodo style grill/smoker. You can go low & slow, or very high temp. Wind & temp have little effect on them. Several brands to choose from, I've had an Akorn for a couple of years now and I'm very happy with it.
