I have an XA, XA1, XA2 (several), XA3, and XA4. The XA1 is only to complete the collection. I use a 2 and the 4 most. The 2 has zone focusing and is sharp enough for me. The 4 has macro and a 28mm lens as opposed to the 35mm on the on the others. With a 35 mm lens and reasonably fast film, (I use 400 almost all of the time), there is plenty of depth of field to zone focus. I find the XA finder to be acceptable, although, admittedly, not extremely bright. I should add that I wear pretty strong glasses for nearsightedness. Placing a black dot on the larger viewfinder opening over the place where the rangefinder spot is increases the contrast. Someone cited an article on this which was found on the net. I think it was Rick Oleson's site. The cameras are so easily to carry that I always have one with flash with me. Other than light seals, I have had no problems. I have replaced the light seals myself. Not a big deal. There is a great website on the XAs, easily found.
I have no idea as to the relatively trading value.
I agree that if you can try and roll or two, at least you will find whether the camera is acceptable to you.
