Initially I was a bit skeptical of that shop name, as it has that "generic scam shop name" vibe, but it seems they do sell the same items on eBay under that name:
Follow local.338 on eBay. Buying, Selling, Collecting on eBay has never been more exciting!

That said, you're effectively paying $45 for them to flash a generic Chinese SiI3112 SATA card with the Classic Mac OS capable firmware, as these cards are less than $15 on eBay:
Interface: SATA. Item Type: Array card. Independent 256-byte FIFO in per serial ATA channel is for host read and write, supporting for two independent serial ATA channels. causing the item not fitting your need.

The only caveat is needing to flash it yourself, though this can be done within Mac OS these days with the custom ROM and patched flashing utility courtesy of

Bloody hell @dosdude1 you're good at this. Nicely done.

The card does need to have an EEPROM that only needs 5V for programming and erasing, which a lot of EEPROMs do but some don't, and you don't necessarily know what you'd get.
Such an EEPROM would have to be replaced, which involves SMD soldering.
So the preflashed card is "safer", but you're paying quite the premium for it.
I would definitely suggest going through eBay instead of their own store, to have extra buyer's protection, just in case.
EDIT: You could also try getting a quality Adaptec 1210AS SiI3112 based card, for probably less than the preflashed generic SiI3112 card.
You do need to disable or remove a small SOIC8 chip, but otherwise should be flashable using the utility.
If you are comfortable soldering, you could put a solder blob across the four legs on both sides of the chip, then heat those until both are molten simultaneously, allowing you to pull it off.
But you could also just lift pin 8 (VCC), or even use thin side cutters (the type used to cut leads after soldering) and just snip that pin, or even just all pins to remove it entirely, any of that should do the trick.

@Carlito's posts about this:
Mine is am28f010. I'm going to try directly programming it when I get the chance since trying with flashrom ended with it unable to find the rom chip. AM28F010 requires 12V for programming, so it can't be done on the card itself. It must be done externally using an EEPROM programmer, unfortunately.

The Adaptec card is of much better quality, so this can be worth the hassle.
I have one myself and it works great, all the way down to Mac OS 7.5 (the earliest Classic Mac OS available on PCI Macs).
