The "AmpKeyer" is another interface that is a little cheaper than the Ameritron and would probably work for you.  Check out the web page: www.theheathkitshop.com/ampkeyer.html

Another possibility for some operators, especially "phone" ops using desk or boom mikes, might be the new Heil Sound products footswitch made specifically to key amplifiers.

It has two switches in the foot-activated mechanism.  One keys the amp, and then as you depress the pedal farther, it keys the exciter; releasing the pedal (taking your foot off it) activates the switches in the reverse order (obviously), unkeying the exciter, and then the amp.  It's pretty foolproof and provides a small time delay between the exciter keying and amplifier keying, in the correct sequence, to prevent "hot switching" amp relay contacts.

But it won't work for CW break-in ops, or VOX ops!
