The tennis ball cannon I use is very very similar to the CSV19 at
http://www.antennalaunchers.com/and I am very very happy with it.
It's not so much a "point above a crotch in the tree and hope the ball
goes through" but "just shoot the ball and line over the tree".

I built the QE-19 from the same site Tim mentioned. *The "air valve"
for it is off-the-shelf so it's a plug-n-play project. *It beats every
fishing rod, bow & arrow, sling shot..... anything I've ever tried
before. *Beats them hands down. *It'll easily clear a 100 foot height
and is accurate after you shoot it a couple times. *It's a little
pricey but that could be spread out if it were to become a club
project.

My impression is that the CSV19, with its modified sprinkler valve,
has a higher muzzle velocity than the QE-19. But overall, I agree
100%, that for me the tennis ball launcher was far and away the best
choice.

I have some friends who are very good with crossbows and they tell me
that I'm wrong, that the crossbow will do the job more reliably and
accurately than my tennis ball cannon, but I don't have a crossbow and
don't really intend to learn how to use one. I don't really want to
shoot arrows into my neighbor's property either. The tennis ball
cannon just made the job so easy, and literally the only gotcha is
that you'll not only send the ball over the target tree, but probably
the trees behind it if you aren't careful. One trick I learned very
quickly: When you see the ball go over the target tree, grab the
fishing line and stop it, then let it go so the ball can just fall
from there. My trees are at the very edges/corners of my property, and
using this trick I was able to ensure that the support lines are also
within the property.

A lead weight from a slingshot or an arrow from a bow will clear most
anything if the string is set up correctly. But both are fairly
dangerous coming down if the string breaks. That's the good thing
about the tennis ball cannons, I think they're safer.

I chose the QE-19 because the components were off-the-shelf and
required no modification.
