Scott, there is no new Super-8 camera on the market. The latest new such product was the danish Logmar. You can detect new old stock somewhere, cameras made in the 1980s or so. Kodak has announced a new Super-8 camera a while ago, we all wait for it with the exception of myself.
Now I am a mechanical guy dyed-in-the-wool. Plastic and electronics are not my cup of coffee, not even the Giotto besides it. My recommendation would be to leave Super in favour of Regular. You have tons of Double-Eight film cameras and projectors on trade places for little money. You have black-and-white stocks as well as a few color emulsions available in Double 8. Pick a Bell & Howell Filmo 8, preferably a turret model, most preferably a GB-Bell & Howell 605. These have three D-mount threads and a critical focuser. Together with a focusing alignment gauge as it was named you enter the macro realm down to objects touching the lens. If you need extension tubes, come back to me.
Else I could offer you different Paillard-Bolex H-8 Reflex models with primes or a zoom lens. My cameras are completely overhauled and I give a two years warranty. Paillard-Bolex pocket cameras are on my shelf, too, B8 and C8 models. But a Zeiss-Ikon Movikon 8 might also be fun to play around with. That camera offers free access to the film gate. You can focus on the film itself (black-white print stock) or on a piece of matted blank film.
