I use an extension tube it is lighter and much cheaper than a macro lens. The problem is you need more light. I have got some good results using it. I did shots that won some awards in a contest in the State I live in. I took best in show and 3rd place with 2 different photos.

It was a benefit to raise money. Anyway, I used the extension tube to photograph a bolt ... lol
Also, I employ a 75 - 300 mm kit lens that comes with the Canon. I say use what you can afford and get creative. @clicked I plan to follow you now...
