About 3 weeks ago, I bought my 1st dslr; a used XTi body. For a lens, I purchased a new Canon EF 50mm f1.8. My question is, should I put down $60 and buy the kit lens that came with the camera. I believe it is the Canon 18-55mm non IS. I figure at short ranges, IS might not make a huge difference. I've seen these around craigslist for about $60. I am really needing a more wide angled lens but can't yet afford the Sigma 10-20. What do you think; is it worth the $60? Thanks for your advice.
