One good thing with pcmcia CF is that you can mount iso's or the entire card as a CD, good to run CD software or install AOS 3.5-3.9 without a CD drive

I have dedicated 1GB cards for some games like Napalm, tho most CD games require more then a mildly expanded A600.
The only game I have not got running from CF is exodus the last war.
Now on topic, I would rather get a adapter from amigakit or vesalia, due to same reasons thomas said. also it is easy to fill a CF card with whatever you want. No need for that mess the seller is putting on it.
