Newegg offers the refurbished Roku 3500XB 1080p Streaming Stick with Remote Control for $27.95 with free shipping. That's $1 below last month's refurb mention and the lowest total price we've seen for this model. (It's a current low for a refurb by $12.) It connects directly to an HDMI port and features 1,000+ channels and 1080p HD quality.
A 90-day warranty applies, but it's unclear who backs it.
