Looking for a super 8 projector? Choose wisely, there are many different brands and models out there ranging from cheap to too expensive. On this page you'll see some listings from ebay, don't forget to ask the seller any questions you have on the projector you're interested in. Did it run recently and consistent, does the bulb work, etc. If the seller doesn't have a clue, bid low and don't pay too much.
After buying a projector clean it thoroughly, you don't want it to ruin your precious super-8mm (home) movies.
Well known brands are: Chinon, Eumig, Elmo, Sankyo, Bell & Howell. My favourite brand of silent projectors is Eumig with variable speed, the 600 series. These are also capable of playing regular-8mm movies.
Don't forget to check if the projector is capable of playing super 8 sound movies if you have sound-striped films.
