There may be a somewhat better solution here. I pulled up the manual for that model Handycam you have and I used to have one that looked a lot like it. The nice thing about mine was it had a firewire port built into it. I was able to just plug the camera directly into the PowerBook I had at the time and import directly into the Mac.
So, rather than spending money on a video transfer kit like what you are looking at, if your cassettes are compatible with the Handycams like what I had, and if you can get one for a comparable price in good working condition off eBay or other venues, this would not only be easier but likely preserve the most detail.
EDIT: a quick note since I'm researching this a bit more. Your camera is a "Digital8" model. There are later models that switched to "Hi8" format and it's on some of these cameras you will likely find firewire built in. According to Wikipedia, "All Hi8 equipment can record and play in the legacy Video8 format."

EDIT 2: Boom! This is actually a later model Digital8 camera and it has Firewire built in.

This would be the old Firewire 400 standard, so you'd still need an adapter to plug it into whatever ports are available on your Mac. Ideally you'd be using Firewire/Thunderbolt/USB-C for maximum throughput.
