At 800 you are right at the entry level price point for most brands. Plusses of going to a LBS and getting an entry level bike are: Everything is new (no deferred maintenance needed to be done), you get a bike that fits you, warranty, most shops throw in free tune-ups for a year, etc. Also it is the end of the season, so you might be able to get a deal on a 2012 bike as the 2013's will be coming in soon. Remember to budget for pedals, shoes, helmet, clothes too.
