I've owned a lot of machines and been detecting since the BFO's were the only game in town. The majority of my machines have been "used", but I would never buy a high dollar top of the line, or close, unit unless it is new. I do radio electronics repair, and a metal detector is a radio, so I can fix a lot of non-working units, but have had to send a couple to Keith Wells that I couldn't figure out. Most detectors aren't even broken in good before they get put in a closet and basically forgotten about, and these are what you want to find, as long as the batteries were removed before they went Rip Van Winkle. Battery leakage is the most common damage in these forgotten units. Component degradation is a constant, and failure can strike at any moment, which is true of any electronics. Used machines have worked well for me, but I'm picky about what I buy, and realize it is always a gamble. I will buy non-working units if the price is right, on the chance I can resurrect them, which I usually can. After battery damage, most other problems are actually mechanical, switches, pots, disconnected wiring, bad battery contact, disrupted board traces, loose coil, etc. Actual component failure usually is with capacitors, anything beyond that and it starts getting complicated, at least for me. All that being said, in the past few years I found a couple of 50ish year old White's BFO's that ran like champs when I put the batteries in, you just never know.
