Hi, bro & sis, which is better? Bosch or Black & Decker for a hammer drill? What should I look for? 450W or 650W? I will need to hang some poster, built a few shelves for books and souvenirs.

Any good DIY book you will recommend? Just browse through the Reader Digest DIY book (RM149) at MPH, not sure is this book the best in the market?

Any help?
