Which kanji book should I choose if I can only afford one?

Hi everyone,

I'm currently studying Japanese and can only afford one more book right now, so I want to make the best choice possible.

I've already mastered both hiragana and katakana, and I'm currently working through Genki I while using the Kaishi 1.5k Anki deck. I'm now looking to build a foundation in kanji.

The three options I'm considering are:

1. The Kodansha Kanji Learner's Course: A Step-by-Step Guide to Mastering 2300 Characters
2. Kanji Dictionary 2500 for Foreigners Learning Japanese
3. Remembering the Kanji, Volume 1: A Complete Course on How Not to Forget the Meaning and Writing of Japanese Characters

If you could only choose one of these (Or none of these — any other suggestions?), which would you recommend, and why?

Thanks in advance for your help!
