The main problem with the DTL 1000 was that the meter used a tiny chain to move the adjustable parts (inside the camera). If this ever breaks, it is not easy to repair. However, aside from that, they were fine cameras. If you need to replace the old light seals, I have written specific instructions for that camera (it has a more complex seal architecture than many similar 35mm cameras), and I'll gladly send them to you via e:mail in a pdf file. I also have a light seal kit that will give you all the material you need to completely re-seal it for $6 (free shipping in the USA and no more than 80 cents to any other country). Please e:mail me at Jon_Goodman@yahoo.com if you need this file or info on the kit. I think you'll enjoy that camera.
