Sorry but we don't keep tabs on which suppliers our members use and likewise they are not too keen at sharing their suppliers with us or the other members :)
Yes, that is true about electronics being one of the most saturated markets on ebay and online in general. You might want to consider selling electronic products' accessories instead for starters.
Here two ways to find out what is selling well on eBay:
1) Check out the popular searches and most popular products on eBay:
Popular searches: Link hidden: Login to view
Best selling products: Link hidden: Login to view
2) Perform completed listings searches for products or brand names to see the conversion rate and average selling price.
To do a completed listings search, simply click the Advanced Search button next to the main eBay search box. Enter your search keywords as usual, and then check the Completed Listings box. Hit search and you'll see historical data for the previous 30 days. Successful items are in green; unsuccessful items are in red.
Hope that helps :)
