Good mid sized tank ?

I agree. If you're already thinking about upgrading, then skip the expensive middle step and just make the jump. In your heart, you probably know that this is going to happen sooner rather than later so it saves you spending on a 4' upgrade and then having to resell everything that is undersized and won't handle a 6' upgrade. If you weren't already thinking about/talking about your next upgrade, then I would go with a 4' 120g. But since you are already looking ahead, save yourself some time, money & aggravation (from having to sell things off when you upgrade).
