Sorry buddy.. don't be bummed out. I know the feeling but the last place you want to "skimp" is lights or filtration.
You can look on Craigs list and also check with your local reef club. Someone may be upgrading their tank or something. I just recently got one for less than 1/2 price because a fellow reefer has an "unplanned family addition" where-as the Tank room was soon to become a "Nursery".
Keep your head up. It will happen if you're patient. While you're waiting, keep saving your money. It's possible your savings will grow to help you get a GREAT deal on a unit when it comes available.
Happy reefing buddy
