How to get started with Ebay?

Okay, I have been thinking about starting an Ebay business. The problem is I don't really have any startup cash because I am in high school (might have to combat this by getting a job) and I do not really know how to find good suppliers and dropshippers. So my question/s is this? What is cheaper to start out with dropshipping or wholesale? And how can I find the right dropshippers and products?

I am also interested in this kind of business. Where are you from ? I guess you should decide what product you want to sell there first.

Anybody got anything?
