Canon tripod is strong enough. I remember from one of your thread, you are using a 60D, right?
The Canon tripod can tahan my 7D with a Tokina lens, or even a 70-200mm f4L, it should be able to tahan your 60D, no problem. But if you want a lighter tripod, you might need to go for carbon fibre one... and 100 to S$150 is stretching the limit abit tight... don't forget, a tripod is only part of the story, a good ballhead or tripodhead is the other part. No point getting a good tripod, the ballhead is crap, your whole camera will still come crashing down.
