As previously stated dropshipping electronics is a tough business...there simply isn't enough of a markup to make it worthwhile. In my humble opinion you need to decide on your product line a little differently. Just because an item is cool, or in demand doesn't mean you can make money off selling it. Instead, I think its actually smarter to sell an niche item, with demand, and not much competition. Before you say thats not possible, trust me it is. You just have to think of things way outside the norm of electronics, videos games, etc.
To answer your specific question, forget about finding a good dropshipping company and focus instead on finding a profitable niche. You do this by finding products that are in demand, with little competition as stated above. THEN AND ONLY THEN, you look for a dropshipper of some quality, reputation, and price. If you can tell me you can profit $1000 a day selling video games, then I will point you in the right direction for a good dropshipper. However, I'm pretty sure if your honest with yourself you can't make that much. If thats the case, then find the market niche, correct product, THE the correct dropshipper.
Hope this helps you/someone/anyone who is considering a dropshipping business.
I've always dropshipped products from DHGate (dhgate.com), have never had any problems, just look for members with reputable feedback, like on eBay. You almost can't go wrong since DHGate only sends money to the seller after you've indicated that the item(s) has/are arrived, so there's no point for the sellers to scam you.
the prices on DHgate are too high, by the time you buy something on there, it wont make you much profit when you sell, coz you will find that same price you get on DHgate on ebay, there goes your profit. Just my lil search though, i might be totally wrong
