Chess Puzzle Books

Hello I am looking for a few good books with tactics and puzzles inside (The more the better). Looking to improve my tactics and want a good, solid, relatively cheap book that will imrpove my game/vision. Currently rated just about 1100 and need to imrpove. What books do you guys recommend?

You can't go wrong with this book.  It should be a part of everyone's library.

That's not a really good book because he treats X-rays as skewers which they are not and a lot of problems are not computer verified for accuracy. Many times the computer came up with a way out of his solutions.

Granted his books were written in the '70s I believe, before sophisticated computers became a thing.
