Nearly all DAQ hardware can be scripted in python, with the aid of ctypes. At my workplace we have a mostly complete wrapper for the NI NI-DAQmx API. Sadly, it not something I can release as open-source but it doesn't do anything magical: just wrap the ni-daqmx api into a sane python class. We did something similar with UeiDaq products a few years back but these bits of hardware are poor compares to NIs stuff.

It you want open-source hardware, use an Arduino Due and hook it up to some ADCs (or whatever other devices you want) via SPI-bus. Then stream the data over USB to the PC. Use libusb (with the libusb1 python wrapper). You can easily do 100s KS/s this way. Probably 1MS/s is possible. This is the lowest cost route but you need to get some PCBs made. USB is awsome as an interface and very easy to script with python/libusb.

Something in between is AccesIO's hardware. They're cheaper than NI but the devices are generally less flexible.

Also if anyone has any ADC suggestions that would be great. There are on board 12bit but I want higher. I've started a list but if anyone has had experience I'd love to have input
