+1 on an old Zetron console. A 4010 with channel cards should work...but may need the memory battery replaced depending on age. Be careful on eBay, many do not include any channel cards.
Motorola consoles are usually well used. Any Motorola gear my group gets rid of is pretty trashed by the time it hits eBay.
Telex gear often requires the dongle for licensing. Licensing and software can be a deal breaker for consoles. The Zetron 4010 will program with DOS or WinXP software, but may retain some usability with the correct tone channel cards without software. Specific HLGT, delay and other settings would need software, but just keying the radio would still work.
