well you always end up spending more when you dont plan, so its good that you are, i would try to wait for a good deal where you are, and get it, you save hundreds of dollars when the little things come with it, like heater, and if it comes with stuff you dont want sell it for a little money, and get what you want, better to plan every detail then spend more money down the road, and defitnally go with the 30G i would have like it better to but i have my 20H for now, soon to be 60
