website design - Is there a free 'Helvetica Neue' alternative? - Graphic Design Stack Exchange

Does anyone know any other fonts similar to Helvetica Neue (free for commercial use)? I’m working on a big website project where ‘Helvetica Neue’ is used heavily. I need a font that looks almost the same, is free for personal and commercial use, and looks good even when used with copytext (e.g. fontsize for copytext = 11px, for headlines = 16px). Also there should be a condensed-font style included (if possible). via website design - Is there a free ‘Helvetica Neue’ alternative? - Graphic Design Stack Exchange.
