Thanks se-r-57,
I've now had a look at that one, and would do the job but the cost mmmmm
US$500-00 and you look like you would need to still buy a cable to go from the interface to your laptop or palm....
Thanks but I think I'll still go for the BlaZt Cable and software with quite a cost saving by the look of it, check out the cost for yourselves guys here's the link.
