I would like a nice wide angle lens and although the quality of the consumer lenses is satisfactory for the time being (well, almost

) I do intend on buying one of the Sigma EX lenses at some point
I quite like the APO 70-300 and it produces a decent quality image, but I would consider the Sigma 28-300 F2.8 to replace the 70-300 unless I can get a L series lens on the cheap
Three of the lenses I definitely would like are the Sigma 10-20, Canon 50mm II and a nice 100mm prime, but I want sharper images straight from the shoot rather than using PS
