It works both ways and depends what your doing. And for a lens to make a real difference in terms of its sharpness you need to spend really big and the lens will also be big. Its a different game mate. The only thing id say with cheap lens's is the aperture is seriously restrictive if your grabbing moving objects. the 70-300 is good for what it is, but the 18-55 kit lens arent great without a flash or in very good light. Plus the 70-300 is a fantastic lens anyway. Unless your a pro with endless pockets your not going to get better pictures at that range with pretty much anything.
Seems like a good deal, but for that lucre, wouldn't it be better to get a lower spec camera and better lenses? I think that is the prevailing opinion; invest in glass first and foremost.
