Electric Treetap v.s. Regular Treetap and Talisman of Repair comboEdit
Note: The Talisman of Repair can (assuming it is placed in an Alchemical Chest or an Alchemy Bag) be used to repair the durability of the the regular Treetap making the Treetap's durability effectively unlimited. The Talisman of Repair and regular Treetap combo has no upkeep cost (it doesn't take fuel like EMC or electricity), unlike the Electric Treetap which takes electricity. So, from a thrifty-ness and even a convenience stand point the Electric Treetap is useless because it has a higher upkeep cost than the Treetap-Talisman combo.
This combo is more convenient than the Electrical Treetap because it does not require the player to return to a power source (which, if the player is exploring, could very well be kilometers from the player), rather it simply has the player place the Treetap and Talisman in his Alchemy Bag for the Treetap to be repaired.
Also Note: Make sure you don't accientially break the Treetap because obviously you can't repair it when it breaks and is lost from you inventory. Remember to repair it when its durability gets low red.
Concerning the Costs of the Talisman of Repair and Alchemy Bag (intended for beginners)Edit
If you have been playing Tekkit for a while, or already see how the Treetap-Talisman combo is cheaper than the Electric Treetap, I guarantee this paragraph will not be helpful to you so just skip it.
If however, you are realatively new, the following paragraph would definitely be worthwhile to read.
Furthermore, every Tekkit player should get a Talisman of Repair very early in the game, because it has the ability to repair any tool or armor, not just the Treetap, thus saving the player both crafting time and EMC (because everytime a tool breaks you lose that tool and therefore that tool's EMC). Therefore the Talisman of Repair should not be counted as an expense for this combo since a minecraft player will need/want it whether or not they decide to use the Electric or regular Treetap.
Also the Alchemy Bag, which is required for the Talisman of Repair to repair the Treetap and all other tools and armor, should not be counted as an expense for the Treetap-Talisman combo because every Tekkit player will need it either out of convenience (it effectively expands the player's inventory by 104 slots) or for a power item (See Usage With EE Power Items for a list of power items that must, like the Talisman of Repair, be placed in an Alchemy Bag to work.)
