Starting a e-business

[UK345]

I am thinking of starting a internet business and wanted to know what your experiences are. My main selling platform would be ebay and some free ad websites I am aware of. I am thinking of specialising in Apple products so things like iPads and iPods. I have not yet found a wholesaler so I need to research that and find out if it's worth my while. As you can tell I've only started to explore this option.

What are your experiences with selling on ebay as a business ?
