Yeah, I've only ran into those in media. They always looked like big, professional style rigs in comparison to the high gauge little bitty insulin syringe.
I'm honestly considering to start using only .5CC syringes. I ran into one a couple weeks ago w/ a tiny tip and only half the barrel I'm used to, and as long as you don't need too much liquid, it felt like they were much easier to manage. I've always been a 31G 5/16 1CC type of guy, but I think a half CC syringe might be easier to handle and lead to less damage. Depending where you're going you can even be successful w/ smaller than 5/16" tip. Can't remember what the measurement is though.
I once accidentally had dozens of 1/2" tips and brutalized myself with them. I attribute that period to my lack of usable veins on my left arm.
