Two tone generator?

Can someone tell me where I can get something to generate a two tone audio siginal that I can inject into a transmitter that doesn't cost a fortune? My signal generator does a single tone just fine, but I'd like to be able to inject a two tone signal for ssb testing.
 

I use my IFR FM/AM 1500, but that is overkill for most. I have it for my repeaters, since it has a tracking generator and spectrum analyzer.

I wonder if you could just use an old DTMF pad? Has anyone tried this?

...and then, if you really get desperate, pick up the phone, punch a number, any number. Most of them are 'two tones'.

Well, I use my PC soundcard, but a simpler generator. It is a simple dialog with two sliders, one for each freq.

Works great and it was free!

I can't find the link for it or I would post it...
