Ya I'm going to wait it out like you say, and I don't think I'll be getting any $400 lights in the near future!:icon_biggIf your on a budget, the T5 lighting is most likely your best all around choice. Before you run out and spend any money, why not wait and see how you make out with the existing lighting? You can always spend more money in the future.
Of course, if money is no object, you can always get a couple of those high end LED modules at about $400 each, and go to town on all the special lighting effects, and be the envy of all your aquarium keeping friends (grin)
