Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"
If you shoot night photography then you should know that a DSLR in this range is not gonna cut it anyways. And further more, you should get a hotshoe flash if you are gonna be shooting "artistic" shots in the still of the night.
Get a K20D if you want good high ISO at a decent price or spend gobs more for Canon or Nikon FF DSLRs.
