I purchased receiver new from DeMambro Radio in Boston $595.00 including adding a Viking Valiant II & SX-101A in the cash. Added all mechanical filters (Collins) and extra tuning crystals -brought price up to $800.00 back then! Receiver stable as hell great, band spread, etc. Terrific sensitivity - very sharp on ssb and cw. Used with G5RV as well as all band vertical. Had receiver from April 1, 1969 - April 1, 1991 with flawless performance. Wish I kept it. If you find it used and good condition with the filters (I had the Collins type with the receiver as stated) then I would recommend purchasing it.
I do a massive amount of swl activity (also a ham - W2FKN). Features are almost overwhelming. Only have a Comet diploe (CHV-5X) at 25' and an indoor discone. Coupled receiver to an external Acer monitor for improved spectral resolution - changed colors, etc. Phenomenal resolution throughout. Label sites, FM stations, etc. with radio. I can tune out and resolve anything - even cw pile-ups from DX with no effort! Yes the toy cost me $13,000, but is worth every penny. Never saw such packaging, instructions, and overall info. Positively 1st class throughout. This picks up anything that emits a signal - use it daily!
