Cellphones, especially the iphone are the best selling items on ebay. However finding a good supplier can be hard sometimes. You need to make sure you get good quality phones and not the cheap knock-offs, otherwise people will complain.
I used to purchase electronics on Ebay, but now I prefer to surf on sites like wallydeal.com. It is great! Low price and great service. Recommend!
electronic and gadget is the most hot saled item in ebay, or anywhere... Try to build your own market with your own item to be success on ebay

Just do the keyword research using Google keyword tool and find the most wanted and less competition product. And after getting that right product , analyse the facts and prices of that product in various online stores then start to sell.
