FleaBay has a pretty decent selection too. I've seen listings for large quantities of various sizes as well as smaller lots. Good luck.....
I just go to my local Tractor Supply and get my 20mL syringes to use to make my tanks out of. No need to wait for online ordering.
You can ask to buy them at the pharmacy in places like Target. Tell them they are for giving a baby or your pet medicine. They charge less than a dollar for them.
How the heck did I get back to 2009? Its way easier just to buy a tank these days.
You could always pm gummy bear! Lol.
Good luck. Any good "vendor"(I hate that word) will have syringes.

If you live anywhere near any farm/ranch/feed supply store, you can buy syringes without any hassle. Folks with livestock use them all the time for vaccinating (etc.) their stock... I'm not sure about online sources; since, all I have to do is drive into town to the feed store. They have a big display case with everything other than the 16cc ones I (think I) need to make (polyprop) replacement sleeves for my (polycarb) V-Core 2.0 tanks... I've found that the 6cc are handy for mixing juices and filling cart tanks, though.
Try your local pharmacy they have all sorts of syringes behind the counter. I picked up a few and they were $.25 plus tax from a walgreens with pointed needles the pointed needles do not work well, but just get the luer lock style ones.
You can also get a flush syringe. Its for your when you have a tooth out, its what I use to refill my carts, and they come in various sizes. Most pharmacies will give them to for free or a small charge.
