José Quintana Trade Rumors

It looks like the Pirates are still in the mix for José Quintana. He could solidify our rotation into one of the best in the NL.
Three names that seem to be attached to a trade with the White Sox are Glasnow, Meadows, and Bell.
The price tag will not be cheap, but what price is too high? I really like Bell, even if we can hang on to the other two, I still don't want to lose him, I think he has big bopper potential.
It looks like the FO is in it to win this year, I hope they can make a reasonable deal happen.
What do you guys think? What kind of prospect package would you give up?
