I agree with that price being way too high. There's currently one listed out here in SoCal for $1K, with a vise. But, like another poster stated, it's all about location. Go look at it, if that's possible. See what it comes with. Look at what else is for sale in a 100-mile or so radius (or whatever is realistic where you are). I think people are using the pandemic and the global shortages to jack up the price of everything.
For reference, I bought an RF-30 clone (Rutland Tool, built around 2009) with a Kurt vise for $975 in Oct of 2020. They loaded it in my truck for me, too (it weighs around 660 lbs). I've spent about $650 or so on tooling, which is on the low end. I needed a stand, so I paid a welder $325 to make a stand, plus another $100 or so for paint, a wood top with sheet metal on top of that, misc. hardware, etc.
I would say it's worth about $200 more with the table is appears to be sitting on, depending on how well-built it is. See if you can get a tool chest under it. You will probably have to spend some time going thru it and making sure everything works well, since HF is notorious for low QC. It will be a nice machine once you have it sorted out. I really like mine.
Hopefully, you have enough info to negotiate a more realistic price.
