I have owned(still have two) several and if you take your time, as you have found, they are fairly easy to work on. Are they worth playing around with? I think so and mainly for one reason - the lens. I find the lens on this camera to be very good and it gives me results, IMO, as good as my Rollei 35 with Tessar lens. Color rendition is slightly different, but contrast and sharpness are right up there. These cameras are "waterproof" and made to go down to 15', but past that and you're on your own. Usually the seals can't hold under the pressure at a depth greater than 15'. You might get by at 20' a few time, but lookout. The main problem with water leaks is actually user error. When people load film into these little guys they must always check the doors rubber seal and the area it comes in contact with. One speck of sand or piece of broken film from a sprocket strip and you got problems. These are excellent boating, beach and rainy day cameras with very good lenses. Worth the trouble? Yup! JW
