You have to realise, if you go to a cheap shop and get it fixed, if something else goes horribly wrong with it, such as the battery life just... Going poof (100%-0% in like 10 minutes (happens sometimes)) - Apple won't fix the problem.

In a nutshell, if you get it done by a cheap company, Apple will not fix, replace or even give advice (depending on how stubborn the shop is) on anything to do with your iPad ever again.
