The cheapest build on s35 is probably DIY from a company such as Rapido or Rectilux.
Here's the Ursa Mini Pro 12K in that configuration:
The main pieces are a Rapiod FVD-16A + ISCO Ultra Star Red + taking lens.
The taking lens in the photo above is a Tamron 45mm (this is the first time I've tried it) but I personally generally use the Nikon 50mm e or my preferred one, the Sigma Art 50mm.
Here are some stills:
