Are you wanting the bike for Cyclocrossing, commuting or general versitility? Hopefully you will have at least a few options to test ride.

I bought a barely used Redline Conquest Pro about 5 months ago and have used it as my winter commuting bike. I feel like a good good components for the cash (105s). I think I paid about $800 which included a new saddle and a second set of brake levers. It is light weight and even with my heavy lights and rack box I can still hoist it up over the carpet at work as I leave it indoors.

I am very pleased with it. Next "treat" will be to get some disc brakes on it. I wanted to be sure I was comfortable with the bike before spending too much on it. Have fun!
