Drop shipping has a lot of competition. Not that you can't make money on it, just be aware of it. If you wanted to drop ship you can research the product sales on eBay by searching the sold listing for items you are looking at selling.
I haven't ruled drop shipping out, but I have too much fun searching for hidden treasures to look into that sort of business model fully.
The main thing that attracts me to drop shipping is in the name. I like the idea of having someone else handle the shipping part especially Amazon prime.
