Based on your search for a Mecer 3KVA UPS, I would recommend either of the first two options in the results: The Mecer 3KVA 1800W Offline Tower Ups ME-3000-VU+ is currently available for R4029 from multiple retailers. As it's the Mecer brand you requested, at 3KVA power rating, this seems like it would meet your needs at a good price. Alternatively, another Mecer model is also listed, their 850VA 480W Offline Tower Ups ME-850-VU available from multiple stores for R823 or R849. Both of these Mecer UPS units seem perfectly suitable to protect your devices from power issues at competitive prices. Let me know if you need any other details on these options!
