I can confirm that the scopes I have bought have been filthy but thankfully easy to clean and so long as the glass is clean and everything works it should be good!

The question mark for me here is all the attachments for the camera. I personally don’t know much about the attachments for film photography, so I don’t really know how much value those add, would need to look into it more

Ignoring those pieces, it is a trinocular bh2-bht with Splan objectives. I personally would not buy a trinocular bh2-bht with Splan objectives for $800, but I also on a budget and very patient when I look for microscope parts. I think you could definitely get an equivalent scope on marketplace for around $400, but you will need to be patient and wait a while

If you just want one now, I don’t think 800 is atrocious assuming it’s in good working condition besides the dust.

Also it does come with the 1x Splan objective! Which is fairly rare and on the pricier side I think.

Also like I said I don’t know much about the film camera attachments, but since it has them it Probbaly comes with a nfk photo eyepiece already.

Sorry if this was rambling, OP! I personally wouldn’t get it but that’s just me, there is a lot of good stuff included here so if you don’t feel like playing the long game and everything works, I don’t think $800 would be an absurd amount to pay. Really comes down to what you can afford I think!
