The Crosslakes aren't bad but as others have said, you can get something similar or better for less. If you get a bike online, have your bike shop retension/retrue the wheels as these internet bikes have machine built wheelsets that often aren't true or have properly tensioned spokes. The 48-16 gearing is a little steep for newbies or those with lots of hills; I'd get a 17 or 18T cog for starters, save the 16 for later. Check the brakes to make sure they are adjusted correctly. These bikes come partially disassembled so you'll need to know how to put the handlebars on, seatpost, saddle, etc. Get a friend that's done it before to help; it'll go a lot easier.

unkwnsldr87, if you live in a large metropolitan area, check Craigslist for deals on fixed gear bikes. Lots of threads here on entry level fixed gear bikes; what's important and what's not so important. One thing that is important is to read the Sheldon Brown website.
