Will, that Heathkit should work out fine for you. Just don't put too much faith in the frequency dial calibration.
You mentioned that you had a digital receiver which was fairly accurate so you can use it to confirm the generated frequencies. For example to check 260 kHz output, set the digital receiver to 780 kHz which is the third harmonic. Tune the generator around 260 until you hear the 780 signal in the receiver and then you will know you are exactly on freq.
Of course, regular AM broadcast freqs can be checked directly on the fundamental output.
