Difficult for me to say Mr Leeroy. I don't know what costs are involved, as in what you paid and whether you would have to pay postage to return it for testing. If they would credit your money back, if it is faulty, could you run to an Elvis programmer instead. I'm not familiar with the fun programmer and can't quite see a reason for running it through a parallel port. Also, why no installation or operating instructions with it.
With an Elvis you can program most types of cards, not just fun and you might want to use the odd gold or silver card. It's all down to choice and affordability, I do appreciate that.
