Miller Multimatic 255 Welder - Bad Circuit Board - stuck in service center

Purchased this machine in March of 2021 from Cyberweld, I have loved welding with this machine. A few months ago it just "died" (no power)... I found the circuit board conductor plate was separating... (board is bad).... took it to an authorized repair center, they said "known problem" ... they have submitted it to Miller .... but have been stuck about a 6 ~ 7 weeks waiting on parts ... with no indication of when will be repaired.
-- We are at the point where it is needful to have another welding machine, I am thinking of ordering an Pro Pulse HTP 220 MTS? .... (I am kind of partial to Pulse Mig).....
-- My Lincoln c300 has been running for years with no problem, just too expensive to order a second one.
