i am worried about what they are going to mess up. not improve. LTE is unlikely to make it to Indian version. It is not going to be useful here anyways. They might temper with the processor or the GPU or worse the display itself. That's what I want to know along with the pricing. As for eBay, if the seller has enough sales and a good reputation, it should be fine. But you need to know that the phone would not have warranty in India.
