Very common, its hard to find a press with a decent distance to the post that isn't enormous and $$$$. I get by with a cheap one and its really hand for lots of aspects of building, even if string throughs are tricky on some body shapes.

Even with a press the bit can wander around a bit meaning you end up with wonky holes. I think some people on here recommend careful measuring and drilling in two stages, front and back. That way at least you can get the spacing nice and tidy on the back of the guitar where you see them.

Definitely one of the more difficult things to get right.
