Thinking of starting a nano reef

[BlueAbyss]

I also have a 10 gallon nano, 70W DIY metal halide. Your cost will depend on what you want / need out of your system. What sort of livestock are you planning to keep? And what size do you have space for? Some tanks are easier to 'work' with... I really wish my tank was 2" deeper front to back (it's only 10" in that dimension).
