If you are looking for a somewhat rugged bike that has flat or flat'ish bars that weighs in the low 20's then some '07 and '08 models would include:
2007 Specialized Globe Expert - with carbon fiber fork, seat stays, seat post

2007 or 2008 Specialized Sirrus Comp ($1000 in '07, $1200 in '08) - a bit more of a road bike than the Globe:

2007 or 2008 Gary Fisher Mendota:

Cannondale also has their "Bad Boy" series.
Giant has the FCR series. I don't find the FCR1 to be quite as comfortable as some of the above, but it is a nice bike. Their new FCR Alliance looks promising, but is $1500.
