I’ve recently been through the same search for an I2S connector and decided on buying from Ricable who are an Italian cable company.
I highly recommend their SUPREME HDMI MKII Digital Video Cable HDMI 2.0 Bandwidth 29 Gbps and Audio I²S interconnect that costs 74 Euro for a 1/2 metre (c. 20 inches) plus add 25 Euro for shipping, see Ricable HDMI I2S Interconnect where I ordered online.
I use it to connect a PS Audio Perfectwave CD/SACD transport and Denafrips Venus 15th DAC and it has performed excellently with me now being close to 500 hours burn-in on the Venus 15th DAC and HDMI cable. I bought mine February 16th and it arrived quickly via Fedex by February 20th.
Ricable offer a 60-day trial period for those who buy directly from Ricable with a a refund or replacement of the purchased Hi-Fi product (unfortunately for the USA there is a return fee). Ricable also provide a lifetime warranty.
There are a lot of interconnects and DIY cable options to see on their website and prices are competitive, hope this helps in your <$200 search.
