Ask HN: Alternatives to Gusto for someone self-employed

Now that Gusto is raising its payroll price to $45 a month for a single-employee company, does anyone have any recommendations for a less expensive service? I need a payroll service because my company is a C-Corp. So far it looks like Intuit Basic Payroll is a good deal at less than half Gusto's price ($21/mo if I prepay for a year).
