If someone you knew had six 741’s, power supplies for each and the controllers basically a plug in and go setup how much BTC would be a fair trade for them if the deal was done tomorrow?
I know they can be bought new with PSU for around 1k each but it will be months before you get them.
I'd consider paying about 8k for it, off course it also depends on your electricity price, as a higher price would mean you need to pay less for the same hardware to break even

6 units = 48-50th
so if you got it in 2 days you would have about 10 days at this diff or around 0.09334 btc back in the first 10 days.
if you paid 1 btc in theory 100 days could or may earn 0.9334 btc
power used is 8000 watts or 8 x 24 = 196 kwatts a day or 6000 kwatts a month at 10 cents = 600 bucks about 20 a day so 100 days = 2000 for power
if you mine 2000 days and diff moves up with price holding you would have 1.38 btc in 200 days or 1.38 - 4000 for power if you had 10 cent power
so 1.38 x 9600 = 13,248- 4000 = 9248 after 200 days or break even and gear in hand.
That to me is the best it would do. so if you had 10 cent power I would say it is okay buy not great.
drop power cost to 8 cents and the deal looks better.
raise power cost to 12 cents and the deal is so so .
snap guess. if this was s-9's they use less power but break more
I would take 5 s-9's because I will get breakage.
So my guess is 1 btc is max price for 6 that making some money could happen.
I would want to pay less if the deal was offered to me say 0.8 btc or 7500 usd whatever is less
