I am a fan of the Penny Press. They are able to provides hundreds or even thousands of puzzles at a relatively cheap price. Their collections, including the Puzzler's Giant Book of Word Game include many different types of games, similar to the king of all puzzles: Games Magazine.
The Penny Press is the poor man's version of Games Magazine, with a large quantity rather than quality. The pages are made of similar paper to newspaper and don't have that crisp feel that the Games do.
There are puzzles in the Penny Press that aren't found in Games Magazine, like the number seek, similar to its cousin the word seek, only with numbers. For an example of some of the great puzzles the Penny Press provides, check out this week's puzzle.
My biggest complaint, however, is that the Penny Press is too big, with too many puzzles. Part to blame is my attention span, that when failing at one puzzle, I quickly move onto the next, leaving half finished puzzles scattered at this all-you-can-eat buffet of puzzles.
Why finish this puzzle when hundreds of others are waiting their turn? I have to work on my self control when it comes to starting what you finish. I can probably attribute the same behavior pattern to my life in general, but because this isn't a psychologist's office, I'll keep it at that.
I have 513 pages worth of puzzles to finish and if that isn't good practice, I don't know what is.
