I have a lightly used Quest M3 (built and delivered new in 2014). This machine has been well cared for, is in great condition, includes all original parts and accessories from the factory, plus two solid state, K-type thermocouples and an Amprobe TMD-56 K-type thermocouple, multi-logging digital thermometer (valued at $125 new). Effectively shelved and unused since 2015 following the purchase of a North TJ-067, but very well maintained and recently vetted for issues (none found). She's running beautifully and ready for a new owner. Serious inquiries only please. Cheers!
