Whats a fair price for an Arcade Card?

[A_Locomotive]

Just curious what a fair price would be for an Arcade Card. Since I won one of the copies of Sapphire in the recent raffle as well as Kabuki warriors in the trivia contest I've got two games incoming that I won't yet be able to play(heck don't even have my Duo-R yet lol) when they arrive but I definitely want to play them, especially Sapphire, man does it looks amazing! I just dropped a none to insignificant amount on the Duo-R I'm getting from D-lite along with a nice selection of games so I'm not planning on buying an Arcade card until likely after the holidays or once my Christmas shopping is all done. Just curious what would be a fair price for one, preferably with its case for ease of storage.

I'd say $25 for a complete arcade card duo

and probably about 30 for a arcade card pro.

Thanks for the info.

I wish I could find an Arcade Card Pro for $30.  I usually see them for about $50 on the 'Bay.  Granted though, they usually have the case and documentation, not sure if that adds to the price or not.

here is a loose Arcade Card Pro on ebay for Buy-It-Now $28+$3shipping, or it says "Make Offer". That is a pretty good deal. Probably wont be there for long.
