PrimeDeal via Amazon offers Prime members the refurbished SteelSeries Stratus XL Gaming Controller for Windows and Android for $24.95 with free shipping. That's $4 below our February mention of a refurb and the lowest price we've seen. (It's also $23 under the best deal we could find for a new unit.) It features analog triggers and pressure sensitive buttons. It requires two AA batteries (not included).

Note: A 90-day warranty applies but it's not clear who backs it.
