If you love your Trek why not blow the $1k on upgrades? Build a rear wheel around phil wood? Powercranks? Change the handlebars? Brooks saddle? cycling computer/GPS? You might even consider getting the bike hacked sandsmachine.com.

real road bike - Try road tires($100), I bet that gets you 75% of what a $1000 real road bike would gets you.

BTW once you spend the $1000 on a new bike you will want to make changes to that bike.
