As already stated those are not drosera seed. Drosera seed will generally be small, black, and almost powdery. Avoid buying seed from any ebay seller not located in the US. In fact, it is best to not buy seed from anyone on Ebay until you get some more experience. The carnivorous plant groups on facebook are a much better source for legitimate drosera seed. As for good varieties, a lot of south african species are a good place to start. Stuff like capensis, aliciae, natalensis all make good species to start from seed. However, I'd generally recommend not to start with seed as a beginner. Seed is a very slow way to get a sundew. Most seed can take a month or two to germinate and from there they will stay as small as a pinhead for a while. Generally it'll take a full year to go from germination to flower if your conditions are good. For that reason a mature plant from an online nursery is a much better choice for most beginners. All that being said if you are interested I have some D. Affinis that are flowering now and I'll have some seed ready in a month or two if you'd be interested in that species. Good luck!
