Rick,
I'd say the best peformance for your buck would be
an R-392, but it doesn't have a product detector.
I've never had a problem tuning in SSB on mine though.
Another rig worth checking out is a Halli SX-122.

Finding a tube rig with a product detector, general coverage,
and for a decent price is getting tough. A friend has asked me to
look for an HQ-180 (preferably a 'C'), and prices have
been astronomical.
