I have had that set up for about a year & really like it now that i'm starting to figure out the camera. The 28-135 IS is a nice walk around lens and I used it shooting from the boat all last summer. I have recently added a 50mm 1.8 and my new favorite toy the 70-200 IS 4.0 L to my bag. I also got mine from B&H. Don't think you can go wrong with that set up.
Couple of shots from last summer with the 28-135.
F/L 135, F-7.1, SS 1/1000, ISO 200
F/L 135, F-5.6, SS 1/1250, ISO 200
Rich, really like the 1st shot of Chris, Nice.
