Anything made by Directive Systems is fantastic. Worked with a friend in Northern VA to put up a complete 6-1.2GHz stack on a tower a few years back. Directions were so easy even we (three guys doing labor and one management type) could do it! They worked really well and tolerated lots of bad ice and snow.
Mine will go up on my raise ranch house this spring. (Bought it used from a guy who had it a couple years on a laundry mast.) I am up on a 400ft+/- ASL hill that will take a lot of wind abuse as its higher than most everything around it. So give me a year or so and will tell ya how it does when not in a hole.
