Sorry for deleting the other post.. checked prices after typing.
>>3118581>35mm film developing kitNo developer or fixer. You have to buy these as well.
Just checked and you can get a developing tank for 20-30eur at ebay. A chaning bag is 30-40 eur. So it would be ~30-40eur for measuring stuff. That's a little too much considering you can get those at a 1eur store. For smaller amounts (~20ml) you can ask any doctor and they give you some syringe for free.
You don't necessarily need a changing bag if you manage to get a room light tight, but I wouldn't want to miss mine.
