Agree with the Buddha on A3000 (It opens up other expansion doors as well) and always recommend supporting Amigakit, but,, these IDE to CF adaptors are a dime a dozen(See I can speak U.S.) I have one in my A1200 and one in my A4000. Both bought on ebay for BA (a poet too) from different but simular Hong Kong gentlemen.
The key is to get a good original CF card and the recommendation of the SANdisk (Ultra II 4 or 8gb) will ensure compatibility once its zapped. Make sure you purchase from a registered SANDisk retailer. SANDisk is a bit more expensive but you know it's quality and you know it works right now. The jiggery pokery bit is about HD Toolbox (3.1 v 3.9) but AORG will help you through that, if u can't wing it.
CFs are sooo quiet and quick and tiny, teanie, itsy bitsy, cutie.. sorry got carried away.
