I have decided to rent a lens for vacation to see the difference. As much as I hate the thought of paying that much money for such a small item, and after owning a business and watching people pay 4 and 5 times the amount for an item. It is really hard to spend that much money on mass proposed anything. Especially just for a hobby.
A TC only works in AF when the maximum lens opening (aperture) is f/4 or larger. From f/5.6 and smaller, only manual focusing can be used if the TC is compatible. Kit lenses have smaller maximum aperture, so you will lose the AF capability on the lens. Manual focusing is not always accomplish easily on a digital SLR. It requires keen eye sight, steady hands and more than likely using a tripod. I don't use my 55-250mm much after I got the Tamron 70-300mm VC which is a much better lens than than the EF-S 55-250mm with a longer reach.
