The folks who are on avg on the fence at this are the ones with (much) larger machines and have more experience machining.
My very personal opinion, thinking back to when I had no sapce (living in a condo) and no spare cash is that I would offer the $1600 after seeing the machines in person. Take along a sample of what you want to work on to see if the work envelope works at all. Twiddle dials, see if the machines are well used or little used (you can tell none of that from photos). Look for hammer marks, dings on the ways, holes in the mill table or vise, all the tell tale sign of maybe taking a pass.
Don't get caught up in the DRO or not stuff, that can be added later at different price points. It won't affect the accuracy of the machine, 'just' ease of use. The machnes do look reasonably well tooled up so you can get going doing stuff right away.
The above is my personal experience going from Unimat lathe to Taig lathe to KC102 lathe and a wierd horizontal mill to an Atlas horizontal to now a King KC20. Thankfully all in the fairly spacy basement shop. Also added a Sherline lathe for tiny work. You have to start somewhere.
My wife taught me a wonderful saying years ago, "f you don't ask you don't get". So make the offer and go from there. You have to know what your personal limit is financially.
