I made a decision similiar to yours when my last "good" Super-8 camera finally stopped working. Rather than buy multiple cameras on eBay looking for one that worked, or paying Bolex-size dollars for a semi-pro refurbished S8 cam, I decided to actually buy a Bolex H16 SB instead.
Since I'm one of those bizarre people who like to project, I've been shooting E100D exclusively. Great film, but its speed (actually exposed at iso 64 to accomodate the narrower shutter angle and prism) on a sunny day is a recipe for ND filters and f-stops smaller than f11. This makes the reflex viewfinder extremely dark, especially when your eyes are adjusted to daylight. Following action can be a challenge. The solution seems counter-intuitive - use the octometer (side viewfinder) when the action/brightness warrants it.
Also, carry a flathead jewellers screwdriver just in case... I had the winding crank knob come loose early one afternoon. Being on a screwdriver-free boat on Lake Michigan made for a long afternoon. Had to wind using the crank's shaft. Slow!
