Nothing special for now, but there are a few really nice ones that I am eye-balling already. Those cost more than what I payed for the entire kit though.
Currently have:
Canon 18-55mm IS f/3.5-5.6
Canon 70-300mm f/4-5.6 tele/zoom -wish this was the IS version, but for 40$ brand new I can't complain.
Thinking about grabbing the Canon 50mm f/1.8 II lens from Tigerdirect as I've got a gift certificate for xmas there and really don't need any computer parts as much as I love to want all the crazy new stuff. Other than the plasticky build quality the reviews state that its very sharp, and I plan on taking quite a few portraits.
