John,

       What do you want to do with it?
       You did not say how many channels you required?

       Thurlby at http://www.tti-test.com/ do the VPS10 4 ch 12 bit 10 
microSec @$135

       Pico seem to want far too much http://www.picotech.com/

       I think that they effectively charge for the 'free' software in their 
module prices.
 
       We really need someone to design a Kit boards that work with the free 
software available!! 

       Regards,

       Chris Chapman

power: from PC serial port

price: $99 maximum ($50 preferred!)
