Won a somewhat used SNL-G-508 off e-bay. Not a bad price, but in its condition it should not have been more than $100.
Although I do have the SNL on CD now that I have a paper version I can scan/OCR and make it searchable.
How cool is this: Type in a part number, get the description back. Or type in a part name, and get a list of PNs back?
I already have the TM10-1562 scanned in and OCRed... this one is next!
