I would like to add another suggestion. Get a cheap Pentax digital body plus M42 to K mount adapter and use the lenses. Running film through the camera is a good idea, but in the long term it requires dedication to shoot film.
Those are all splendid lenses that will give excellent results on a digital body. There are lots of pictures on this site taken with Takumars mounted on digital cameras. Check out the reviews section.
Look out for a used K100D (six megapixels) or K200D (ten megapixels). The Takumars are all manual but this means that they work almost exactly like they did on early Spotmatics. Open the aperture, focus, stop down aperture, take meter reading, adjust shutter speed as needed, shoot, repeat. A bit of a learning experience for youngsters with their new fangled auto focus lenses, but familiar to Spotmatic users. Unless it's one of the later ones with open aperture metering, I should hasten to add.
In short, unless you need some cash, hang on to those Takumars. Using them would be a lot more rewarding than a few hundred dollars.
