Welcome! You are correct that a bike for touring will serve you well for a long commute (is that 25 round trip, or each way??). There are LOTS of good options out there. I'll throw some out, and if you have questions, we can (try to) answer them:
Surly Cross Check (cross bike, but takes racks)
Surly Long Haul Trucker
Jamis Aurora
Novara Randonee
Rivendell Atlantis
Trek 520
Specialized Tricross
Bike Friday (particularly the crusoe and new world tourist)
Bruce Gordon BLT
In the (way more) expensive category:
Seven has custom touring bikes
Co Motion Americano
Custom Rivendell
Independent Fabrications (independence or club racer)
Good luck!!
