Chrome lining isn't needed, and an alternative is a melonited barrel, which are becoming more common but are still going to cost a little more too, IIRC.
If a melonited barrel is out of the question, why not just get chromed? Less risk of rusting, easier to clean. It's better for the overall life of the gun, and in my opinion, is a good investment.
