I am pretty set on the XA, its small enough to have it with me at al times and wont be a burden during any part of the trip, even with another camera.  I think if I only had the XA I wouldnt miss shots, but I would miss the big negatives of MF or the convience of digital.  I like my Rebel, but the crop factor isnt too exciting, so instead of buying a wider lens to go with the Rebel, I started thinking of what kind of camera (film and/or digital) I could get to go along with the XA for the same (or less) money - what would be the better buy?
 
The types of photos I take are more like landscape/building shots, which tends to mean wider angles (again another disadvantage of the Rebel).  I dont take many photos of people other than an occasional photo of myself and wife for example.  
 
There is no perfect camera, or even a perfect camera for a specific application really.  I am gathering ideas and suggestions on what would be a good choice on a camera purchase - someting different enough from what I currently have and also useful to travel in Europe etc., I may or may not find it.  
 
Currently I am considering wide angle cameras like the Bessa L, or a compact MF like a Fuji GS645S, or something digital...
