Diamondback Edgewood ‘09

It features:

• narrow tires for road conditions/speed
• lightweight but solid frame
• adjustable stem height and angle
• double suspension (front and back)
• different sizes
  

The original seat is a little uncomfortable.
The pedals seem cheap, and gear switching isn't exactly smooth.
Overall, it's a great value for the money. It can be used as a commuter bike and for leisure.
Available from Sports Authority stores.

Canon EOS Rebel XS

Canon EOS Rebel XS or XSi are probably the best portable DSLRs available.
I opted for the XS because I did not really need the extra features (and cost) of the XSi.
Why portable? It's lightweight and relatively small compared to other similar models. This can also be a downside, as the grip might feel too small, or the body too cheap, made of plastic.
The greatest advantage over older models is the Live View, which is nothing like the display on point-and-shoots. It allows you to evaluate the exposure before shooting!
Now for the bad news: you can't focus and expose in one shot. You have to press a separate button for Live View focus, and then press the shutter to take the picture. The shutter won't focus in Live View mode.
It's still great in low-light conditions, when you want to check the exposure before taking the photo, and a live histogram is available!

Kryptonite 4 x 9 U-LOCK

Walmart carries the Kryptonite 4 x 9 U-LOCK for $19.97.
It seems solid enough for a regular bike, in a low to moderate crime neighborhood. In for 2.
It's 13 mm (not 15), and it seems to be a cheaper version of the KryptoLok® series 2 Std.
I'm combining this with a chain, just in case.
