18-55 vs 16-45?

[Paul]

Hi,

Just wondering if any one has compared the 16-45 to the 18-55, As an 
18-55 came with my K10D, but i havent opened it yet as i was going to 
seel it on Ebay, but i dont really like the size of the 16-45 and am 
wondering if i should just keep the 18-55. I dont really use zooms a 
whole lot in this range, but its nice to have one up my sleeve.

Any comments appreciated.

Thanks.
Paul
