Get the 2000
The cruising standart is a 2000EU. We run AC, battery charger, TV, DVD, anntena, and 40 watt lightbulb. Separately it will power a microwave oven and an electric coffee pot. The 1000 will not do all this. The difference in cost and weight are minor compared to the added power. Yes, the 1000 will run a battery charger but why stop there when you can have much more.
