Newegg offers the refurbished Sony PlayStation 3 40GB Console, model no. CECHG01-40GB, for $69.99. This $10 mail-in rebate cuts that to $59.99. With free shipping, that's the best price we've seen for any refurbished PlayStation 3. (It's also $50 under the lowest total price we could find for a refurb elsewhere.) It includes a Sony DualShock 3 controller. Rebate expires September 30.
A 90-day warranty applies, although it's unclear who backs it.
