I can't recommend a "good brand" per-say, for syringes, but I would have to *highly* recommend O-Ring syringes. These last longer than regular syringes with rubber tips. Glide better and last longer. The standard ones tend to get stuck easily and can be a pain to use... so they kind of turn into one time use syringes.
-I don't hand feed, but I've done some research on syringes!

Yeah, I agree, there is no "brand" of hand-feeding syringes...You can use either a specific oral-syringe, or you can buy disposable leur-slip syringes that have the tip on them, or you can buy disposable leur-lock syringes that have no tip but you rather buy special feeding tips you screw onto them...But whatever type you buy, it should ALWAYS be an O-Ring syringe, as if it's not, they'll just end-up getting stuck and you'll squirt a huge amount of formula all at once into the baby's mouth/all over them.
Can I ask why you're needing a hand-feeding syringe? Are you planning on hand-raising baby birds? I only ask because it sounds like you don't have much experience doing so, if any, and I'm wondering if you understand everything that is involved in doing so, such as the strictly necessary formula temperature range, the ambient temperature range of the Brooder you're keeping the baby's in (both of these temperature ranges are not optional, as if either is too low the babies will not be able to digest the formula and will develop yeast infections and crop-stasis, and if the temperature ranges are one degree too high, the formula with cause crop-burns, and the ambient temperature will cause heat-exhaustion, dehydration, and death)...Also, the proper hand-feeding technique as far as what side of the beak to start on, going over the tongue and across to the opposite side of the back of their throat towards the crop entrance, feeding/pushing the formula in-rhythm with the baby's feeding-response, etc. If you don't know what you're doing you will kill a baby bird easily and quickly, instantly if you aspirate the formula into their lungs. And even an adult bird will suffer from crop-stasis, crop-burn, can be aspirated easily, etc. So I'm just making sure that you're not just attempting to start hand-feeding birds without knowing the most important things that are not at all optional...
