Cannondale t2 and t1 are no longer being made.

As for the Koga Miyata World Traveller mentioned previously, Fly to Amsterdam, pick up a bike for yourself, and tell your other half there is no money left in the bike budget. She will have to hitch hike.

Phone around if you live in a city with lots of bike shops and ask what they have in touring bikes. Then get out and test ride them. One will feel just right.

50 lbs each on a bike is a pretty major load. Are you taking camping equipment? If you are staying in B&Bs and 3 star hotels, you should be able to get by with 30 lbs each. Take "quick dry" clothing that you can wash in the sink in the evening.

Get your gear, bikes, racks, panniers soon, and try some test rides and overnight tours close to home. It is nice to have the wrinkles ironed out before you leave home.
