I had an XR2 for years. Loved it. The rewind knob broke, and it would cost more to repair than another one, so I bought another off eBay - and the seals went bad. I got a kit to replace them but didn't dare it (anybody do it CHEAP? Like less than I paid for the camera? If I supply the seals?)
It's definitely built consumer grade but is just such a well thought out, fully featured and nice handling little camera. In some ways I even preferred shooting with it (when it worked) to my LX, if for no other reason because the XR2 has AE memory lock.
