Are you willing to ship international?
Why you selling though? What's the real reason?
"more than i can mine" sounds kinda bs (no offense..)
It's most likely because he may not earn is money back. The difficulty is going to keep rising making it harder to mine.
Btw, it takes a very long time to break even on these.
I don't think you've thought this through.
If that were the reason, then the safest path would be to acquire as many of these as possible, and mine with the highest possible hashrate before the next diff jump.
The more hashrate you have today at X diff
You should take a look at the thread that goes into detail about this. It explains it would take a very long time at the current difficulties rates to break even. Considering the difficulty will rise then that will mean it takes longer than predicted now.
Anyway, I was just pointing out a reason, there's still profit to be made of course and if set-up correctly can be very beneficial.
What's the shipping costs to Europe?
