A couple of old slide projectors have turned up in my local paper but I am unable to find much information searching google. I mainly use 120 but also the occasional 35mm. I am fairly new to the film and my focus has been aimed towards hand printing but I do plan to shoot with transparency films and a cheap projector could be a handy addition.
Kodaslide home projector circa 60's hand operated.
There's not much to go wrong with the Kodak, I don't think it even needs a tray.
Depending on the tray the Ham&eggs uses or comes with I would be leery just 'cus it's a Hanimex.
If you're looking for a decent machine find the last generation Kodak or Leica. For 120 you're going to look long & hard. the good ones ran into big $$$ unless you could find a 120 version of the hand operated Kodak.
I'll tell you a secret: it is not uncommon for Rollei 66 projectors in working order to sell for about 100 on ebay.de. Shipping is expensive and risky, though, as they are very heavy and their glass condenser lenses are extremely fragile. I'm very happy with my P66S. It is a very simple and rugged machine.
I went over to see the Kodak as it was just a few miles away and ended up spending a good hour chatting to this nice old boy about his days of wet plating with his father. As a result I ended up taking the Kodaslide (which works fine) and a box of his great grandfathers wet plating bits and pieces, like plates, frames, masks, ruby oil lamp and ceramic dishes for not much more than a couple of bottles of wine.
