I'm also beginning to look for a counter with very similar requirements. Studying eBay the other day, I came to the conclusion that an HP 5384A would be a good option, combining small size (compared to older rackmount counters), adequate resolution, an external reference input, and availability at fairly low prices. I decided that I probably don't need to hold out for one with the TCXO or OCXO options, since I'd generally only use it on my bench with my TBolt's OCXO as a reference, and it simply switches between its built-in reference and the external one rather than phase-locking its own reference (so I wouldn't be using its internal reference, and thus its performance wouldn't matter). -- Mark J.
