- Would you pay $50 USD + $8 (US) shipping for this adapter?

  Commentary: The serial connector is the main bottleneck on lowering the price.

- What is your favorite USB connector:

  - USB Type-B (full-size)
  - USB Mini-B
  - USB Micro-B
  - USB Type-C

  Commentary: I think USB Mini-B has a good balance between connector strength
  and size. USB Type-C might be more popular though.

- Would you pay $10 for a high-quality plastic case for this serial adapter?

  Commentary: I think the exposed PCB has a nice aesthetic. I am also concerned
  about the clearance between the Dreamcast serial port and the Dreamcast AV
  port. It is deliberate that this serial adapter PCB is nearly as narrow as
  possible.

- The maximum configurable Dreamcast SCIF speed is 1.5Mbit/s. However, it may be
  possible to achieve faster speeds by overclocking the SCIF via the SCIF
  external clock input. If a 1.5Mbit/s adapter is priced at $50 USD, would you
  pay $100 for an adapter with that can transmit and receive at an overclocked
  2.0Mbit/s?

  Commentary: I think this is a funny idea, but I doubt people want to pay for
  it. It is almost certainly a better idea to make a G2 bus (modem connector)
  peripheral for this instead.

- Do you think there should be a similarly-priced serial adapter product for
  Sega Saturn?

  Commentary: Sega Saturn is slightly more interesting because there are three
  completely separate serial interfaces on the same connector. This is a perfect
  use-case for the FT4232H quad-channel UART chip.
