The 18-55IS is MUCH better then the non IS and not a whole lot more expensive really.. For real cheap there's a 50-250IS(I think that's it) you can find used for a good price, if you don't already have it the 50mm f/1.8 is fun lens to play with and overall the 28-135IS is most likely the best bang for the buck... If I was you though I would try and stretch out and get a Tamron 2.8 lens of decent length. Like a 17-50 or something.
