I'd stay away from the old RC generators unless when very low on money.
Many of them are complete pieces of crap, too. I've got an old Simpson that's suppose to do sine, square, triangle to 5 MHz. Once you hit about 2 MHz, triangle becomes sine, sine becomes "WTF is this?", and square becomes "heavily distorted sine". Amplitude, frequency and symmetry controls are so ridiculously nonlinear that you spend a very long time fighting with the controls (and there's interaction between the latter two), and the sweep and modulation are so bad that they're useless. I was able to make it usable for very limited purposes by modifying the circuit in a few spots, but it's still worse than the cheapest shit imported via fleaBay.
Don't let yourself think that just because it's been around for a while, looks good and has a recognizable name that it will even meet its shitty specs.
