I bought mine (SN #963) in April of 2021 for $2500. Chrome chassis w/ the black tread-plate and blue indicator light. Mark series transformers. No transitional features.
I've also experienced this with gear that I've sold recently. People called me out for listing it so high and told me to how crazy I was, and that I was dreaming that I would get my price. I got my price every time. Sure, it's taking longer to sell gear than it did in mid-2020 but stuff is still moving more quickly than pre-pandemic and if you are patient enough then you will get your price on something like this.
My two cents? I'd start with a list price of $4000 hoping to get an offer in the mid-3000's.
