I had one, not a LX Jr, that was the MX. Of the 2, Program + or MX the MX has much better build quality. Until the LX the MX was the pro level K mount body. The program + is fine as long as the electronics hold out. Mine developed issues with the film advance, could not find anyone to repair it. I have a number of K mount bodies, MF and AF, in MF program + level I find the Chinon CP7 work well with all my K mount lens includeding AF. It has program mode, manual mode, aperature perfered auto exposure mode, but no shutter speed perfered mode. Intergrated film winder, about 2 FPS, takes AA batteries. Right now I have a Pentax 28 to 200 AF on it, which of course I use in manual mode. Viewfinder is clear.
