Wow you guys have cheap supplies the US! Cost me $48 for 100 syringes.I switched to short needles a long time ago. Agree with Veronica. There is very little chance of poking thru. Now I'm using 5/16" needles, 31 gauge on Leo for over a year. I get them at Walgreens. 100 syringes for $18.
I just bought a new box today at Walgreens - same price $17.99 for 100 count.
