Yes, it is definitely cheap. I am using it but I bought it from them about 1 year ago for close to $200. The warranty is supposed to be lifetime from Convergent Systems, which is good. Just make sure you keep the receipt. Convergent does not require you to show receipt, but this is just in case Convergent does not recognise this card as "theirs" and you need to go back to AF.
Do note that although the standard and elite pro ones are the new packaging, this ultimate card is still the old packaging. Not sure why, but was previously told the new ultimate cards have some problems.
Anyway, for $56, you don't have much to lose.
