Omega Engineering (www.omega.com, info@om*.co*) and others make data acquisition units that will take raw input in this range and convert it to an rs-232 or parallel output. These hockey-puck sized units are very handy for this type of thing, but they will run you about $250. Aside from that, yup, you're pretty much brewing your own. I don't know exactly what your requirements are, but if you're thinking analog (which seems the gist of your post) then by all means, man, get digital! -Will (I have nothing to do with Omega, aside from that I buy their stuff).
