Endless amounts of choices, anything really. That's the beauty of the internet you can find nearly anything you want to buy and sell. I don't understand, ANY niche you decided upon can be profitable. Unless you decided your niche to be something like professional Bonzai tree tool kits, you're safe with nearly anything.
I wouldn't even be able to list off the top of my mind %25 of the niches that are available. It depends on what kind of niche you're talking about too. Niches can be tiny, small, medium, large or gigantic. What worked for me was to start from the largest category of niche and divide little by little until I find something I like.
For example someone who decided to be in the niche of selling Double AA rechargeable batteries it would be something like this:
Gigantic niche: electronics
Large niche: batteries & chargers
Medium niche: rechargeable batteries
Small niche: double AA rechargeable batteries
Tiny niche: Duracell double AA rechargable batteries
You can do this with nearly any possible category of niches you can find. I found my niche by browsing through wholesale lists and doing my own research with wholesale price, popularity, eBay price, profit margin, risk, size, and supplier. I have a database of products that I can compare, contrast and pick only the very best ones on top of that list. This works for me anyways.

I guess I was hoping for a magic search trick, lol. I'll keep at the long hard slow and steady way.
