By starter lens, I'm assuming you mean the 18 - 55 lens.
Most Canon shooters swear by the Nifty TWO FIFTY (55 - 250 lens) and the Nifty Fifty (50 mm/f1.8). Between the holy trinity of lenses (including the 18 - 55 mm) and assuming that you're not doing more than taking normal everyday snaps, that's about all you need. The Nifty Two Fifty is so coined because it costs around $250 to get that lens.
The Nifty Fifty lets you take really nice close-up pictures with that creamy (bokeh) background. It costs about $130 in the US and on special, you can probably pick it up for $100.
For comparison...
I hope you do. Adorama, B&H and
Amazon should stock it...
