is there a type of injection instrument which is fast and fairly painless?

I know there are some because I've seen them, but I can't tell you where you may be able to get one. Most people have found that they don't really help all that much and the regular needles don't hurt anyway.

I seem to remember it's called something like Pen-inject. You can always call the people who make caverject and ask them. I'm sure they will know.
