Rock A Deal has the refurbished Motorola SPN5689 Dual USB Power Adapter W/ Micro USB Cable Charger for $5.50 with free shipping. Supports simultaneous charging, and has surge and IC chips.
Says nothing about output so safe to assume its only 1A per port so forget about charging many tablets or fast charging 1A designed devices. Would have bit if it had concurrent 1A and 2.1A ports.
