Awesome, I didn't pay full for mine either but more than you did obviously lol, although mine was still brand new. I've been toying with upgrading my lights as well but with a retrofit kit instead. As for everything else in my set up they will all be upgraded, getting a custom sump, skimmer and reactors. But as of now all the upgrades are costing more than the actual tank was lol although these upgrades aside from the LED's will be transferred to a larger tank down the road.
