There are a few things to consider when purchasing a used back such as warranty.
It can have minimal captures, but if it is not covered under warranty it can cost you more in the long run.
Phase One allows you to add warranty to both in and out of warranty digital backs, but of course if you add it after the warranty expires, you pay a premium and have to wait 30 days before using it for a repair. In warranty renewal per year $1,199 and out of warranty $1,799 (classic).
That being said, Phase One IQ140's are currently priced new @ $19,990 Classic and $23,990 Value Added.(description of warranty and coverage

As a side note We do have a IQ140 pre-owned with Value Added Warranty remaining if you would like to check with us that is priced well.
