Here is another option (one that I bought from):
BLUNT TIP LABORATORY PIPETTING NEEDLES
Scroll down to the second group of needles, with the above heading.
You'll want a 17 gauge at smallest, in my experience. Smaller gauge number = larger bore. 15 gauge will handle even straight VG. I got the 2" needles, but the 4" would be more useful for taller bottles.
They can be used with any luer tip syringe, including the ones they sell at Wal Mart for 25¢ apiece. Those come with something like 24 gauge sharp needles which are useless for our purposes, their bore is too small. Just toss them.
Also, those el-cheapo syringes have graduation marks which easily smear off (but, they're disposable).
I use mine primarily for DIY juice mixing. Great with a 1ml syringe, can't get along without it for accurately pipetting flavoring and such.
