These old HP function generators - all the "digitally controlled analog" ones - are incredibly good function generators; I have yet to find any other that comes so close to doing exactly what it says on the tin with few non-ideal nasties like distortion and phase noise. These are, in my opinion, the ideal function generators for anybody who doesn't need AWG.
However, that's way too damn much for one. I'd pay a bee's dick over $100 if I were desperate for a function generator.
