Do yourself a favor and DO NOT BUY CHEAP LENS'S. The lens is the most important component besides the body. People upgrade bodies all the time but a lens will last a lifetime.
Besides buying a cheap lens will probably get you a lens that isn't fast in terms of focus speed or pulling in allot of light. Putting a slow lens on that 3100 and you'll find yourself cranking up the ISO ending with grainy shots that look horrible.
