Analog Input

[jsmoker]

I'm looking for a way to take differential inputs at once with a range of -15 to +15 volts.  I usually work with PICs but they only have unidifferential inputs with a 0 to 5V range.  Ideally I'd use some NI-DAQ with Labview, but that's kinda out of my personal budget, while PICs and ICs are around $3-$5  Anyone have any ideas?

The MAX1033 (http://www.maxim-ic.com/quick_view2.cfm/qv_pk/4941) can do +/-24 volts...

You can probably get a couple free samples from them.
