So, I'm launching my personal portfolio site, and I'm currently titling with a free font called Alte Haas Grotesk. I probably don't even need to point out that it's ... er ... quite Helvetica-inspired.

I'd love to buy a sans-serif font with a similarly gentle rounding aspect (not looking for anything as direct as Helvetica Rounded).

I shouldn't mention my budget for this purchase isn't too liberal, so the more affordable the recommendation, the better.

Thanks in advance for your suggestions!
