Hi there and welcome!Hi there, I have shot at buying a 20075315 for $70 used, which I see is the 40" Gen 2. Based on the info here, I'd need to remove the slanted drip plate, remove the water tray, put in the bottom rack and toss a 9x12 foil water / drip pan on it. That sounds fine but I'm wondering if there is anyone that could help me figure out what I need to be wary of with this unit, used.
I've seen a lot of talk about putting a PID on it and I see those are about $150. Do the heating elements often need to be replaced too? If so, can someone tell me the cost there? And do any of those mods need to be soldered, because I have no experience or tools to do that.
Guess I'm just wondering if I'd just be better off buying a new one or if this is actually a good deal for $70 used.

As long as the unit runs you should be OK. The major failure areas are the electrical connectors that connect the wires to the heating element and the safety rollout limit switch. That's a $7 order on Amazon to get hi temp connectors if needed and that problem would be solved.
If you want to go the PID route its a simple rewire where you cut 4 wire ends and splice together to make 2connected wires. At that point the wiring skips the controller on the MES and feeds power directly to the heating element hence the need for a PID controller to now cut power on/off.
I always say the best MES is a free one or a used one for like $40-$50 rewired with a $150 Auber PID slapped on it. Will outperform 100x over anything masterbuilt makes brand new :)
