"An accelerator would be nice indeed, but still limited to 128MB by the CPU slot. This RAM board also has the advantage of being much cheaper"
Not really, the A2000 accelerators have much more than the 8MB limit of the ZII space.

Not saying that this cool card doesn't have it's space in the market, judging by the fastlane prices on eBay.
