So I went around looking for lenses. No amount of online research beats physically holding the product if not using it. I don't like the feel of the Tamron 17-50 one bit. The focus thow is too short. Almost as short as the kit lens. Though my worry with the kit lens is the fact that the dront end of the lens extends/contracts while focusing, resulting in a slight shake.
Unfortunately the Canon EF-S 17-55m F/2.8 IS is FOUR times the price of the Tamron (Non-VC), so way out of budget.
I think i'll do some more tests with the kit lens and then figure out the upgrade.
