Let the search begin

I have decided to retire my Aleoca XT and will be searching for a replacement!

Some of the criteria/requirement I would like my next commuter to have:

• Disc brakes!
• Second hand (So if it is stolen not so heart pain!)
• Aluminum frame (Less weight)
• Rigid fork (Less weight, no bobbing=less effort wasted)
• 7 spd/21 spd
• Not a GT (Too attention grabbing for thieves IMHO)
• About $300
