(they give them away for free for kids science fair projects.) It's pretty limited but it may do what you need - 4 analog inputs and 3 digital and sample 240 times per second, serial interface. A few years ago they were selling a slightly different version for like $10 (no housing, supply your own cable) and I picked one up. Surprisingly capable little device, but I never used it on anything significant. The only problem for Alan with that one is: "Note: These starter kits are not CE approved and, therefore, are not available for shipment to European Union countries." It seems to be the only one in their range with this note, so hopefully the others are CE marked.
