There have been a few threads asking where to get IDC connectors for 6-pin ISP headers. I just got a new Mouser catalog and noticed that they now carry them. Maybe they've been there for a while on Mouser's website, but they dont exactly have the best search function in town, so who knows. :roll:
Anyhow they're $0.96 in single quanities... Page 835 in catalog 619.
