I'm a bit on the cheap side and also haven't been willing to jump in and have any stippling done.

I go to the local sporting goods store and get this grip tape stuff that's meant for baseball bats, tennis racquets, etc. and just wrap the grip. Doesn't cost much, easy to undo or redo, and the stuff I use doesn't leave a sticky mess. Plus, you can wrap it thin and barely change the size and shape of the grip or layer it thick if you want something a little bigger to grab hold of.
