I have seen the WuG AT-611s going for about $150 BIN on eBay recently.  I believe the guy who has most of them is in Ontario, Canada.

I was able to score a nice Wandell und Goltermann AT-611 SLM for 75 bucks a few Nearfests back.  Has 400 Hz and 2.7 kHz filters and a selectable USB/LSB product detector.  Tunes from about 4
kHz 18 MHz.  No AGC but otherwise a really good all round receiver for VLF to HF. Mine apparently came out
of AT&T long lines service, must have been used for FDM multiplex cable system monitoring.  Only draws 20
watts, I power it with a little 100 watt inverter in my Tacoma and drive to electrically quiet locations where it does an amazing job at receiving VLF with just my mobile Hamsticks as an antenna.  It's also my CW receiver of choice lately on HF.  I use it to give everyone semi calibrated signal reports on the Old Milrad voice and CW nets on the weekend.
