The key with eBay Pulse is to dig right down into the sub-categories. e.g. # eBay Pulse > Home & Garden > Holidays, Cards & Party Supply > Cards & Stationery
will tell you that
1. sympathy assortment
2. graduation invitations
are popular - both of which you could definitely source from Chinese suppliers.
Another example is: eBay Pulse > Toys & Hobbies > Robots, Monsters & Space Toys > Robots

Obviously these ones are a bit more obscure (unless you really know your robot toys!) so you'd then have to go and look these up on eBay/Amazon/Google product search etc to find out what type of products contain these keywords.
Lots of people don't know about digging deep into the categories on eBay Pulse like this, so it's a great way to get some ideas.
I've heard bicycle-related stuff is really hot right now, and eBay Pulse seems to indicate that that's the case too:
eBay Pulse > Sporting Goods > Outdoor Sports > Cycling

The other thing to try is "As seen on TV products". If you search for this in our directory, we have quite a few suppliers offering these items, and they tend to sell really well while they are being advertised.
Hope that helps,
