Eileen, the other lens is EF-S 17-85mm f/4-5.6 IS USM, and I read a lot of people complaining about its quality. I bought it anyway because it has the perfect numbers to be a walk around lens. On the 100mm macro lens, I have mostly read good reviews on it, and I guess I am just not a lucky guy .
Well, after $35 shipping sending them in, and after some hassles with the customer support, I am a happy guy again .
