got this diy kit in hong kong (Holga Store) for $40 HKD = $5.60 CAD = $5.16 USD
(saw some on ebay if you want to try it)
took me around 2 hrs to finish since near the end, the film winder wasn't working so had to walk a few steps backs to fix it
- comes with a screwdriver
- instructions with Chinese and English but there's you mostly follow pictures that aren't explained very well
- got to be careful with the plastic since once you scratch it, you can't fix it (or buy a new kit)
- there's a counter for your exposures
- in the middle is one of the parts you have to be careful of, the spring is very fragile
- once you close the flap, the shutter won't work, works as a on/off button
- comes with a strap but i didn't like it
Conclusion:
- be careful with the springs, i accidentally bent one of the springs so the shutter sometimes will not close properly
- learn how a film camera works
- reasonable price
- no batteries needed
