I agree with the people who mentioned WorldWide Brands.
1. He provides a list of dropshippers that is actually maintained by a staff. (unlike most of the lists you buy that are crap). And yes, I used to do EBay and dropshipping before I realized that affiliate marketing was sooo much less of a headache.
2. There is also a ton of free info on product sourcing you can read and watch even if you don't sign up. He explains the business model, etc., so you understand what you are doing. For instance, he explains that reputable distributors who will dropship or sell small bulk lots will require a tax id, etc.
I do promote their affiliate program too, because it is always fun to sell something you actually believe works, and they pay on time. Commissions are decent too. Dropshipping is not my main niche, but with rising unemployment I see rising interest.
Do I have a link? Oh yeah I do. I am only posting it because you asked (or maybe that was the voices):
