Meritline offers this Multifunction Network Cable Tester for $2.99, with free shipping. That ties our August mention as the lowest total price we could find for a comparable tester, this time by $3. This unit tests RJ45, RJ11, and Cat5 connections and features an LED work light. A 9-volt battery is required (not included). It's available in black or white, but color selection is random.

Expect this item to take two to three weeks to arrive.
