uh well he didn't say anything about the difference in prices.
Neither did he compared it against FF + the brick 
Anyway, back on topic, I also recommend the Tamron 17-50. Constant maximum aperture of 2.8 across the focal length is a really plus. More valuable than the IS on the Canon 18-55 IMHO. IQ-wise the Tamron is very sharp. The only down side is the AF noise, but most of the time it focuses fast enough that it's not an issue.
